Solid-state accumulators are very cheap, their producers are actively working on increasing capacity and reducing the cost of gigabytes of memory. While it's too early to talk about the appearance of hard disk drives with SSDs, the scope of their storage is actively expanding. Vikoristannya hard drive in the role of system wear in the computer or laptops to bring impersonal benefits, to that varto look at the most recent models, the camp on the cob 2017 rock.

Criteria for selection in the TOP SSD drives 2017

Specially for enthusiasts, SSD builders create high-capacity storage devices with a PCI-E interface, building a rich storage capacity. However, for ordinary coristuvachas, such outbuildings are not narrower than cicadas, and the stench is not disturbed by the accessibility. Even for the price of one flagship SSD model, you can pick up a whole bunch of bad games for an hour system block. Our material is assigned to budget SSDs, which form the bulk of sales in retail trade.

• Format and interface. Candidates were looked at for folding the vibrator, vikonanі in the standard form factor 2,5 " and twisted interface SATA3. The stench is the most universal: it’s suitable for a team who chooses a PC from scratch, so it’s necessary to breathe new life into a computer or a laptop, purchases of a kіlka rokіv to that.
• capacity. "Golden mean", camp on the cob 2017 rock, є total 120 or 128 GB. What is enough, to put it on the disk Windows system, As well as a package of professional (office, engineering, graphic, etc.) software. 64 GB - already a little, and 256 - already look not so budget. If it's not enough for someone, you can search for the version of the model from our rating, it is equipped with a large memory capacity.
• Price. The upper plank of the SSD vartosti bula was taken to the amount of 5,000 rubles. Whenever you choose a new PC and get ready to buy more - then choose to upgrade to models with an M.2 interface or buy a larger storage device.
• yakist. All models that have been in the TOP SSD drives 2017 budget class, gained a positive reputation in the market. To select the best ones, we analyzed reviews about applicants in online stores and on thematic computer forums.

Rating of budget SSD 2017 - TOP 7

At the TOP SSD accumulators of 2017 of the budgetary level, models of 128 GB were consumed, which, according to the higher criteria, showed up better than others. A place in the rating is assigned to them according to the price index, characteristics and speed indicators.

7 month -, 4280 rubles

Intel 535 is an inexpensive mid-range SSD from a leading manufacturer. Vin May 120 GB of MLC type memory. Chipset accumulator - for a long time known bagatami SandForce SF2281. Tse not herself best solution on the market, but in general the reputation of the chip is positive. Golovny yogo nedolіk - tse schilnіst underestimate the speed of work, if the memory is occupied. That is why it is recommended to try three times, if you want 5-10 GB of a free space.

The real disk speed when tested in CrystalDickMark is up to 470 Mb / s in sequential reading mode. The last record allows you to expand up to 200 Mb / s, which is not so rich, but a little more, lower for HDD. Applications swidkodіyu - up to 80,000 IOPS (input-input operations per second), in reality - lower (60-70 thousand).

6 place - Kingston HyperX Fury SHFS37A, 3216 rubles

The Kingston HyperX Fury is one of the most affordable, but not without exception, solid-state accumulators. The memory is made up of 128 gigabit MLC chips made by Micron (8 chips). The accumulative controller SandForce SF2281 manages, which is "famous" for low speed, if the disk is busy.

We carried out detailed testing specifically for the SSD model. In the course of the new Bulo, it reached close to 510 Mb / s in sequential read mode and up to 140 Mb / s - writes. Trochy, but tolerable. The test of the zavantazhennogo "pіd zav'azku" hoarder showed the speed of 470 and 85 Mb / s, when reading and writing, obviously. The speed of the robot was 64,000 operations of entry and exit per second.

5 months -, from 3200 rubles

Transcend SSD360S is a budget storage device, which will be the best solution for an inexpensive PC or laptop. Vіn creations with vikoristannyam MLC chips, єmnistyu 128 GB leather. The memory of Micron victories is celebrated. Controller - SiliconMotion SM2246XT.

Behind the bags of testing or speed, the Transcend SSD360S builds up to 510 Mb / s in line recording mode. In the sequential reading mode, this indicator drops to 180 Mb / s, but even more in the case of a budget hard drive, it does not work. The speed of the code is close to 45000 IOPS, which is due to the low cost of the controller and other factors. However, such an indicator is good for a cheap SSD, but in a pair of HDDs it is simply magnificent. And at the same time, in the swidcode of the disk, you can find the swidk_st and chuyn_st of Windows OS in the process of work.

4 months -, 3675 rubles

A-DATA Premier Pro SP920 is an inexpensive SSD drive for a computer that boasts good price and performance characteristics. Vіn promptings on the Marvell 88SS9188 controller equipped with DDR3 cache. The memory is accumulated with Micron MLC chips, with a capacity of 128 gigabytes of leather (total 8 chips).

Speed ​​of line reading A-DATA Premier Pro SP920 up to 530 Mb / s, which is even worse. From the record, everything is not so miraculous, but not bad: close to 190 Mb / s per second. Looking back at what Windows often reads data, what you write, and when you write - then not in sequential mode, such an indicator can be called good for a budget SSD. Real swedcode - close to 60000 IOPS.

preamble

I do not stop repeating - in order to develop a good choice of technology, it is necessary, if you want to understand the subject area in warm rice. Know the characteristics of your technique, you collect the characteristics. Know how and how characteristics are injected into the work of technology.

Buying an SSD drive on the right is more folded lower for the uninitiated. A lot of the unobvious, attached to the surface. These stats will have the important characteristics of SSD disks redeemed. It will be explained how the parameters of the SSD disk are poured into yoga life. The material is great for obsyagom, oskіlki the topic is foldable.

There are a lot of letters here, but if you have to be patient, read everything to the end, then it will be easier for you to read it, and buy a better SSD drive. If you don't like too much reading, then check the shortened version of this article.

entry

SSDs stop being expensive and start saving data. For the rest of a couple of years, especially in the middle of 2013 and the beginning of 2014 years, the prices for SSD drives have decreased, so you can put such a drive in a whole original computer. With all the speed of today’s SSD disks, it’s such that they give the greatest increase in productivity in a windowed penny.

For 120 - 150 dollars spent on a good SSD drive, you can take the increase in real productivity more low for the same money spent on the processor or on the RAM.

On the availability of SSD disks without plunging into the crisis of 2015-2016. In 2017, SSD disks were costed at a level of 2.5 "HDD, though adjusted for capacity by a factor of 4 (128 Gb SSD was costed at a level of 500 Gb HDD). In 2017, roci SSD disks became three times more expensive than a standard HDD.

Characteristics of SSD drives

This part of the article will describe the most significant characteristics of SSD drives. Technical parameters to increase or decrease the speed of SSD disks.

Main characteristics of SSD

These are the parameters of SSD, like the world's largest vplyvayut on the life of the quality of disks.

Virobnik

SSD drives are made by many companies. More companies sell them under their own labels without producing (OEM). Ale, there are only a few more companies whose discs can be bought safely and hopefully.

• Intel. The company jointly with Micron releases flash-memory. In this way, to destroy your disks from your own memory and choose the best copies of memory for your disks. Not vipadkovo on your discs give 5 years of warranty.
• Micron(trademark Crucial). The company jointly with Intel releases flash-memory. In this way, to destroy your disks from your own memory and choose the best copies of memory for your disks. Intel's opinion is that Micron (Crucial) focuses on the budget segment of the market. Lower price, less warranty term. But the wheels are good, although the speed does not shine.
• Samsung. One of the leaders in the SSD market. Moreover, not only for the obligatory sale, but also technologically. The company manufactures flash-memory itself, control your own. Drives are 100% wet - and memory and controllers, all your own. While in the budget series EVO 850, some models can have third-party controllers (Phison or Silicon Motion).
• Plextor. Japanese company famous for its laser drives. In fact, it's not like that to rob an SSD - it's made for it by the Lite-On company. Ale disks are good. On Marvell controllers. Plextor is not just a touch, ale and swidk.
• Corsair. An American company with a high quality of various products - operational memory, Blocks eating. The company's products are aimed at the so-called "enthusiasts", people who are ready to pay more for a higher quality and speed. However, their budget models can be even more average in terms of speed.
• SanDisk. An American company, one of the leaders in the selection of flash drives and SSD drives. Partner of Toshiba company in the manufacture of chips in flash memory. In this way, disks become their own flash memories.
• Toshiba. Japanese Company In this way, disks become their own flash memories.

SSD disk capacity

Builders of SSD drives indicate the difference in the specifications of the models of their drives. Therefore, first of all, you should buy a swedish disk - respectfully read the yogo specifikatsii, it is possible to sort it out, which you looked at, not such a swedish one, as you ochіkuєte.

That vipadok if rozmir may mean.

There is one more feature related to the capacity of SSD drives. Establish groups of models by capacity, but not all models in the same group can have the same capacity. Butt. Group capacity 120/128 GB. Some models of the group can have a capacity of 120 GB, and others 128 GB. Why is it related?

On the right, in fact, all the disks in the group can have a capacity of 128 GB, and on some models 8 GB are reserved to prevent the removal of the middle ones in flash memory, and to replace the broken ones.

Some of the collections can be not so much improved in capacity and in the lines of life zastosovuvannoy in your flash memory model and that's why you need to make such a reserve. It would be nice to build up such a reserve just for greater hopefulness. For example, in Intel disks, the quality of flash memory is already high, the prote company is reinsured and the reserve is redundant.

Ticks in Disk Controller

Crushing controllers are vvazhutsya Marvellі Samsung MDX. Details about controllers are given in this article.

Degradation of the speed of the record

Reduce the speed of writing to the SSD disk, after that, as soon as there will be more backups and after the backup, the data will be deleted. This is a record in the re-recording blocks of memory. More details about it in retail.

Other SSD Features

encryption hardware with support for the TCG Opal 2.0 and IEEE-1667 standard. Tse gives the ability to vikoristovuvaty hardware ciphering ale keruvati them from the OS. For example, you can change the CPU when using Windows BitLocker.

Zakhist vіd vtrati eating. Some models of SSD disks may be attacked by a rapt attack. Just sound the capacitors, charging some of them on those disks, completing the necessary write operations in the middle of the memory.

interface

SATA

Today (2014) all SSD drives are manufactured with SATA 3 interface. motherboards ah installed SATA 2 controller (SATA 300) and navіt SATA 1 (SATA 150). Can you install a new SSD drive into such a computer?

Obviously you can. However, it is necessary to understand that in any case a new SSD drive will see real speed significantly lower than its passport characteristics.

Modern SSD drives usually can handle read operations at over 500 MB per second. And the recording speed is over 400 Mb per second. This speed can be fully implemented on computers with a SATA 3 (SATA 600) controller, for which the practical data transfer speed limit is approximately 570 Mb per second.

But SATA 2 controllers have a practical speed of about 270 Mb per second. Vіdpovіdno for SATA 1 controllers is even lower - less than 150 MB per second. So, how about you put a new SSD drive in old computer, then wine will be more practicable lower vzagali can.

So for a new SSD drive, you need to buy new computer? Ni.

Є Є Є іnshі mozhlivostі to gain povnu shvidkіst on the old computer. You can install a SATA 3 controller on a PCI or PCI-express board. І then connect the SSD drive through the controller.

PCI-express

In addition, at the same time, models of SSD disks have already appeared, as if they were prepared for a PCI-express board, for example Plextor M6e. So you don't need anything more to buy, just insert the disk card into the PCI-e sockets and that's it. In PCI-e slots, you can install an M.2 form factor SSD, or through an adapter card from M.2 to PCI-e.

M.2 (Next Generation Form Factor, NGFF)

Also, at the same time, there is a new, larger swedish interface for peripheral buildings- M.2. You can buy an M.2 adapter on a PCI-express board and then install an SSD drive with an M.2 interface. Fortune-telling disk Plextor M6e, Just such an option - PCI-express card with an M.2 adapter, on any disk with an M.2 interface.

The new M.2 interface (Next Generation Form Factor, NGFF) is essentially a PCI-express bus, only changes in roses - in adaptation not for expansion cards, but for small outbuildings. SSD drives in the M.2 form factor are already on sale. This interface is responsible for data exchange data exchange rate, which is higher than the practical limit for SATA 3 - 570 Mb per second. Specification for the M.2 interface transferring 4 lanes of PCI-express. For SSD drives, the M.2 form factor has 2 PCI-express lanes, so theoretically the speed of exchange with the drive can reach 2 GB per second.

memory

There are two types of flash memory (flash-memory) - NAND and NOR.

NAND memory type NOR, depends on the fact that the cores are combined into blocks and processed by blocks. At that hour, in NOR, the leather coat is processed individually. NAND memory can take more than an hour to access to the middle memory, but it is much cheaper with the manufacturer.

During the selection of SSD disks, flash memory (flash-memory) of the NAND type is replaced.

NAND flash drives

Memory for SSD drives is made by only a handful of companies - Intel and Micron (large manufacturing), Toshiba and SanDisk (large manufacturing), Samsung, Hynix.

The first such memory was created by Toshiba in the late 80s of the last century. This is the rank of the oldest NAND flash maker.

According to the type of pinout in the housing of microcircuits and remote access from the side of the NAND flash controller, it is divided into two types:

• Synchronous and asynchronous ONFI. Її manufactured by Intel and Micron, Hynix
• Asynchronous Toggle Mode. Made by Samsung, Toshiba and SanDisk.

Types of mediated NAND flash memory

Today (in 2014) in SSD drives, NAND flash-memory with three types of cores is used:

• NAND SLC(Single-level cell) - flash memory in one physical center to store one bit of information.
• NAND MLC(Multi-level cell) - flash memory in one physical center that stores two bits of information.
• NAND TLC(Triple level cell) - flash memory in one physical center that stores three bits of information.

The difference between these types is different in the fact that with the increase in the number of bits of savings in one commissary, the number of memories in pererakhunka is changed to її єmnіst. Tobto, mentally seeming 128 GB MLC memory cost cheaper than 128 GB, but SLC type.

However, you have to pay for everything. With an increase in the number of bits per cell, the number of cycles in the recording changes, as it can be seen in the middle. For example, SLC type memory can be up to 5000 - 10,000 rewrite cycles. And between recordings for MLC memory - up to 3000 cycles. For memory type TLC, the limit is even lower - 1000 cycles of recording.

Therefore, with an increase in the number of bits per one cell, the short term of life of the middle one is taken into account. Ale, at the same time, the security of the record.

In 2017, you can talk about the transition to the TLC memory. Already more than half of all SSD disks are prepared in memory.

Basic parameters of flash memory for SSD

Main characteristics of flash-memory for SSD drives:

1. The number of cycles in the record, as you can see, is a single center of memory. This parameter defines the term of life and validity of flash memory.
2. Technical process behind the preparation of crystal flash-memory.
3. Type of media in flash memory.

The other and third parameters of flash memory should be directly added to the first parameter. The deposit is like this:

• Changes to the technical process change the term for the life of flash memory.
• Increasing the number of bits in one company changes the term for the life of flash memory.

To remember the type MLC mother term life is less than the memory type SLC. The memory is made according to the 25 nanometer process technology, in terms of life more below it is made according to the 19 nanometer process technology.

Єmnіst (rozmіr) memory

Specify in gigabytes. The peculiarity of the SSD is that the disks of greater capacity give great speed to the exchange of data, especially for an hour of recording. The difference in the speed of recording between a disk of 120/128 GB and 480/512 GB can reach two or three times.

For example, a disk with a capacity of 120/128 GB can, when recording, give a maximum speed of less than 200 MB per second, and a disk with the same model, but with a capacity of 480/512 GB, will give a maximum speed of recording over 400 MB per second.

Such a difference is made by the fact that the controller of the SSD disk works with memory crystals one hour (in parallel). And in one model of the disc, the same crystals of memory are found. The difference is in the quantity and the difference in the number of crystals. Less memory crystals - less parallel operation - less swedishness.

It is not necessary to stray memory crystals and memory microcircuits. In one microcircuit, one can have up to four memory crystals. So in disks of different capacities, the number of microcircuits can be the same - 8, but the number of crystals will be different.

Builders of SSD drives indicate the size of the speed record in the specifications of the models of their drives. Therefore, first of all, you should buy a swedish disk - respectfully read this specification, it is possible to expand, which you see is not such a swedish one, as you check.

So, if a person reads a test review on the Internet, it says that the disk XX gives speed to a record of 450 Mb per second. I buy a disc model. Install and independently show that the speed of the recording is acceptable for less than 200 Mb per second. And on the right, it's all about reading about the 512 GB capacity model, and buying the 128 GB capacity model.

Tsya retail is growing in the world of that, as the market appears new 128 bits of crystals of memory, natomist 64 bits. Seemingly simple, since SSDs are built on 64-bit memory chips, then full read / write operations are possible on disks with a capacity of 240/256 GB. And if a disk is selected on 128 bit memory chips, then the full read/write operations can only be performed on 480/512 GB disks.

For example SSD drive Crucial M500 selections on 128 bit memory chips. This line has 4 models:

• 120 GB - recording speed 130 MB per second.
• 240 GB - recording speed 250 MB per second.
• 480 GB and 960 GB - 400 MB per second recording speed.

How do you keep the difference in the speed record between the youngest and older models more than three times. Wanting to save the price of the same disks. For a little wine, a lot of crystals of memory. Prior to Crucial's speech in its 2014 model, the M550 had vicorist crystals of different bitness. For 128 and 256 GB models, 64 bits of crystals are used. For 512 GB and 1 TB models, 128 bit crystals are used. For rahunok tsgogo changed the difference in swidkosti between younger and older models.

There is one more aspect to deposit in the capacity of the disk. The greater the capacity of the disk, the theoretically the greater the term of the yogo service. Right in that the middle of the flash-memory can be seen obmezhene number recording cycles and if the limit is reached, for example, in the middle of the MLC type, the recording was broken 3000 times, out of the way.

All controllers of SSD disks change the number of cores during recording, in order to eliminate the number of cores. For the drawing of victorious, one can remember. Obviously, the less the disk is occupied by the data and the programs, the controller has more opportunities to draw the core and the memory will live longer.

Large disk capacity is the simplest way to increase the free space on the disk. Let's say that the programs and data you take is 100 gigabytes. If it is placed on a disk of 120 or 128 GB, then the disk will be the whole occupation and few other ones will be available for drawing. However, if the disk capacity is 240 or 256 GB, then more than 50% will be available for drawing. In such a rank, the ambition for the middle will be richer lower and there will be more trips and equal deductions.

inspectors

The computer cannot take direct access to the flash-memory, which is in disks, memory chips, and the controller chip is installed. The following microcircuits are issued by a small number of companies:

• SandForce. The next company is LSI. SandForce controllers, for example SF2881, the widest. They dominate in the segment of budget SSDs. On these controllers, SSD drives are produced by Intel (models 520, 530).
• Marvell- Both 88SS9187 and 88SS9174 controllers work in high performance SSD drives spring pickers, Zokrema Micron (Crucial), Plextor, SanDisk. For example, one of the best seen SSD drives in the world - Plextor M5 Pro, Crucial M500, Crucial M550, Vicorist controllers Marvell88SS9187, 88SS9189. The company released a swedish controller for the interface with NVMe support (M.2).
• Indilinx. At the same time, the company has OCZ and the remaining model of the controller is called Barefoot 3. Apparently, these controllers are mostly found in OCZ disks.
• LAMD (Link_A_Media Devices). Shvidky, but rarely wins the LM87800 controller. For example, it is victorious in Corsair Neutron disk models. The company was bought by the Korean Hynix and its controllers win only in pairs with the Hynix flash memory.
• Phison. This company has long been familiar with its controllers for USB flash drives. In the rest of the hour, it began to attack the market for SSD disks. There is a budgetary solution for the selection of SSD disks - controller, firmware, board design. Її controllers vicorate in budget models, for example Corsair LS, SmartBuy Ignition 2.
• MDX. The controller of Samsung's distributions is broken into її disks.
• Intel. Some models of their SSD drives have an Intel-based controller. All server models S3500, S3700, as well as the Intel 730 model are focused on the business segment of the market.
• Silicon Motion. Another company promoting budget controllers for SSDs. From the point of view of productivity, there is nothing visible.

Vіd controller to lay different characteristics of the SSD drive. The speed of work, the term for the life of flash memory, the stability of the life of data.

For example, Marvell controllers give high productivity with operations on large blocks of data. This is just the way the drive appears on disks in a real robotic computer. The Intel controller focuses on high productivity in the minds of a large number of parallel requests (server-driven model).

And the controllers of SandForce have an unacceptable feature - after the disk is filled and the speed is cleared, the record is not rotated to the cob value (if the disks are empty). So the speed of the work itself decreases with a heavily loaded disk. At the same time, the SandForce controllers give a high speed record for easily squeezing data, for texts, documents.

The skin controller has its own peculiarities. Its strengths and weaknesses. How do you have songs footwear to an SSD drive, then when choosing a model, there may be a sensitivity to the features of the controllers.

Inexpensive SSD drives

Inexpensive SSD drives are usually made on SandForce controllers, and Phison is actively working on a couple of other drives in this segment.

The reason for this situation is that the offending companies LSI (SandForce) and Phison propose new solutions for the preparation of SSD drives. There is not only a controller, but also firmware to the new one, as well as the design of the board for mounting all the fillings.

In this way, the maker of ready-made disks does not need anything else to work the cream, as it is to solder the parts onto the board and install the board into the case.

TRIM

For SSD disks, HDD visibility is important, as it affects the speed of the recording. In HDD, the recording is written "over" the old data. Blocks of the disk, which were previously misplaced by the data, and then the data were removed, are simply indicated as valid. If it is necessary to record a record, the HDD controller will immediately write to the number of blocks.

When using flash memory, blocks, which were earlier cleared of the information, were cleared before recording. It should be done before the hour of recording, blocks were broken, the speed of the recording is greatly reduced, even if the controller needs to be prepared for recording (clear).

The problem is that the operating system traditionally does not work with the file system in such a way that when the files are deleted, the blocks on the disk are cleared. Age on HDD disks was not necessary.

Therefore, when using SSD disks, the effect of "degradation of productivity" is blamed. If the disk is new and all blocks of flash memory are clean, the speed of the record is higher than the temple, passport. And then, as the disk will be reloaded, and after the second part of the file is deleted, it will be re-recorded at a higher low speed. Through those, the disk controller has to clean up flash memory blocks before writing new data there.

The decrease in the speed of recording in re-writing blocks of flash memory can be even higher. To a value close to the speed of recording HDD disks. When testing SSD disks, it is often necessary to carry out a special test for reduced write speed in recycled blocks.

To combat this phenomenon, the new OS added the TRIM command to the ATA disk. driver file system when the file is deleted, run the TRIM command from the controller of the SSD disk. Following this command, the controller of the SSD drive clears the numbered blocks of flash memory, but to background mode, In breaks between read and write operations.

Winning this command allows you to rotate the record's security for re-writing blocks in flash memory. However, not all operating systems support this command. And only shodo fresh versions:

• The Linux kernel is starting from version 2.6.33.
• Windows 7, 8 and 10.
• Mac OS X starting from version 10.6.6 (but for this version you need to install an update).

Until now, WIndows XP (like Vista) is popular and does not support this team.

A workaround for older OS, using alternative, third-party programs. For example, you can either use the hdparm program (version 9.17 and later) or the proprietary SSD drive builder program, for example the Intel SSD Toolbox.

For two models of SSD disks, for some, the degradation of the speed of re-spinning blocks is less pronounced than for others:

• Plextor M5 pro.
• Plextor M5S.

Firmwares for these disks can frequently clean up dead blocks without the TRIM command. Reinforcing the security of the entry to higher values, but not to the new passport security of the entry.

Є disk models, which are used after the completion of the TRIM command, are not rotated until the new passport security record.

The TRIM command is most often used when changing to a RAID array.

Note! With victorious functions, it will be impossible to replicate deleted files!

SSD disks by virobniki

I especially subdivide all selections of SSD drives into two categories - large and all other. Large symbol - ce Intel, Plextor, Corsair, Samsung, Micron (under the Crucial trademark), Toshiba, SanDisk. Companies that sell good and custom SSD drives. The skin has its own advantages, for example, Intel, Samsung, Toshiba, SanDisk and Micron roam disks from their wet flash memory. And Samsung, in its SSD drives, won't only have a good memory, but also a good controller.

Ale, in principle, you can buy a disc, whether it be from seven companies, without going into details.

Anything else to complete the great list.

Intel. The company jointly with Micron releases flash-memory. In this way, to destroy your disks from your own memory and choose the best copies of memory for your disks. Not vipadkovo on your discs give 5 years of warranty. Some of the models are still on the power controllers - that is 100% Intel - these models are like Intel DC S3500, Intel DC S3700, Intel 730. Intel disks are better, but the company is mainly focused on the business market segment, and that's why the disks are on the road.

Ale її disks cost their pennies. For example, server SSD disks DC S3500 and S3700 do not only improve memory, but also functions like food storage, expanded checksum rechecking to save data. To rob them even with the help of saving data.

Micron(trademark Crucial). The company jointly with Intel releases flash-memory. In this way, to destroy your disks from your own memory and choose the best copies of memory for your disks. Intellectual Disk Inspection is based on what Micron (Crucial) focus on the budget segment of the market. Vykoristovuє your memory and controllers Marvell. In 2014, the company is releasing a disc that could become a new hit (similar to M4) - Crucial M550.

Samsung. One of the leaders in the SSD market. Moreover, not only for the obligatory sale, but also technologically. The company itself manufactures flash-memory, the controller is also its own. Drives are 100% wet - and memory and controllers, all your own. Become the first half of 2014 roku model Samsung 840 Pro the best-looking SSD drive in the current market segment (drives for high-end computers). The speed of this disk is already dependent on the capability of the SATA 3 interface.

Plextor. The Japanese company is famous for its laser drives. In fact, it's not like that to rob an SSD - it's made for it by the Lite-On company. Ale disks are good. Intel-Micron memory or Toshiba and Marvell controllers win. famous model Plextor M5 Pro don't be surprised by those who are no longer young and in 2014 they are left with one of the best SSD drives. In 2017, the company is one of the leaders in the market for the speed of disks with M.2 disks of the M8Pe G (N) series.

Corsair. An American company with a high quality of various products - operational memory, life blocks. The company's products are aimed at the so-called "enthusiasts", people who are ready to pay more for a higher quality and speed. The company has several model lines - GS and GT disks on SandForce controllers, LS disks on Phison controllers, Neutron disks on LAMD controllers.

SanDisk- it has a good variety of flash memory (common with Toshiba) and current models of SSD disks from the company demonstrate even higher productivity. The company has a long and successful history of flash storage devices of various types (USB flash drives, memory cards).

Toshiba- she has a better knowledge of flash memory (spilne z SanDisk). The company has a long and successful history of production and flash memory and HDD disks.

SSD Life Term

The hour, which SSD drive will be used, in a wild way is determined by the type of flash memory. That is some kind of middle class victorious and for some kind of technical process a memory is prepared. More already, it was written, the largest resource is for the middle SLC type, it was possible to go MLC and find TLC.

What does the limit on the number of cycles of recording mean in the practical sense? How can you approximately estimate the possible term of the life of that other disk?

Let's take a smart disk in which the MLC flash-memory is built according to the 19 nanometer process technology. It is acceptable that the recorder of the memory is indicated for it by the recording limit of 3000 cycles. This is an example for MLC flash-memory prepared according to technical processes 19 or 20 nanometers.

On the basis of memory, the disk capacity is 120 GB. The 3000 cycle limit means you can burn your disc 3000 times. If you will keep the day full of yoga, then clean it up again and on the next day, you will fully restore it, then theoretically remember to live 3000 days. Tobto more than 8 years. If you record only 60 gigabytes per day and only use a disc once every two days, then the term life will increase to 16 years.

Obviously it's oversimplified. Ale realized that the term flash memory life is great. If we take a disc based on TLC flash, with a limit of 1000 cycles of recording, then we give the theoretical term for the life of the disc, at least 3 years, for you know that the wine will be stored again every day.

Therefore, in all of these scars, the recording limit is gradually reduced, there is no serious basis.

You can also independently estimate the term for the life of the disk, knowing the type of flash memory, how to write it in this disk. You can more accurately indicate that, as you have information about the memory binaries, the one that flash-memory binaries indicate write limits on their products.

I have found a lot of disk types, in the specifications of disks, indicate the explicit rank of the write limit on the disk in gigabytes per day. For example, Samsung in the specifications of the 840 Pro disk writes: "5 years of warranty hope for the ability to write to a disk no more than 40 gigabytes per day.". And the Micron company, for its Crucial M550 disk, specifies a recording limit of 72 terabytes, or approximately 66 gigabytes per day for three years.

Prote, in 2015, Samsung gives a 10-year warranty on current models of the PRO series.

In 2017, I can tell you with my best knowledge - I’m waiting for disks, as I have installed more than 3 years before, I didn’t break into them. True, I never installed SmartBuy disks. Only Plextor, SanDisk, Samsung, Toshiba.

How to continue the life of an SSD drive

More space on the disk. Chi do not "hammer" yogo pohnistyu - shob schob on the disk bulo vіdsotkіv 20 - 30 of the free month. The presence of a free month allows the controller to check the removal of the middle memory. The whole place is guilty, but it is not marked, it is not assigned to any partition of the file system. Before speech, the presence of such an undefined mission, which allows you to not fool around with the TRIM drive.

Uninterrupted power supply. If you are trying to install an SSD in a great computer, try to connect the computer via UPS (DBZ). Like an SSD in a laptop, keep a close eye on the battery - do not allow the laptop to be turned on for a full battery discharge. SSD drives do not like rapt food. With randomly turned on food on the disk, you can save data in the middle of the flash-memory. As an option, you can buy a disk model in a yakіy є zahist vіd vіdklyuchennya zhivlennya (Power Loss Protection).

Chill. SSD disks (like HDD, like electronics) do not like overheating. The temperature of the disc is higher, the temperature is more svidet, the viide is out of tune. If you install an SSD in a laptop, then you only need to rely on those that the designers of your laptop have transferred the possibility of sufficient heat input to the disk.

Otherwise, install the SSD in your favorite computer, then you have "untie your hands". The least you can do is to convert a metal converter from 2.5 "(SSD drive) to 3.5" (drive box in the case). Through the metal of the adapter, the heat from the disc will pass to the case. However, for discs in a plastic case, a metal transition is made of marnium.

In the context of cooling, a great plus is the aluminum case of the SSD. As a disk of rozrobleniya on rozum, then the metal case vikoristovuetsya like a radiator for the introduction of heat into microcircuits.

It is possible to install a fan in the same place - in bagatioh cases, there is a space for a special fan, which blows the box for disks. Some cases have a fan.

Do not need to defragment. Fragmentation of the file system does not reduce the speed of the SSD. That's why you don't take away the win in security for defragmentation. However, by defragmenting, you will shorten the life of the disk, for the sake of increasing write operations.

Installing an SSD on an old motherboard

You can breathe life into your old computer by replacing the HDD with an SSD. All disk operations will be two or three times faster. And the disk operations of the computer are too rich - launching the OS, launching programs, opening files, editing files, etc.

If you have an old motherboard for a SATA 2 (SATA 300) controller, then a new SSD drive is not practical with newer security. There are two options to improve the camp:

• Buy a SATA 3 controller on a PCI or PCI-e board.
• Buy a mountable SSD drive on a PCI-e board, like a Plextor M6e.

Wanting, in my opinion, it’s easier to get rid of yak є. In real life, the difference in speed between connections via SATA 2 and via SATA 3 may not be great. It will appear less on operations with readings of great obsyagivs of data distribution on the disk sequentially. І vіdpovіdno at the last record of the great obsyagіv danih. In practice, sound and write and read in small amounts in the prevіlnih (nonsequential) areas of the disk.

However, mounting an SSD drive on a PCI-e board is generally a good idea, as it will work better if connected via a SATA 3 controller.

Expanded pardons when using SSD disks

pardon persha

Moving a large number of files to a special magnetic disk (HDD). Some people install only the operating system and programs on the SSD drive, and transfer everything else to the HDD drive. Folders of time files, browser cache folders, documents and navigate the entire profile of a koristuvach.

Roblyatse in order to save space on the SSD drive and save the term of your life for the change in write operations. For example, folders of timchasovyh files in tse post_yn_ recording operations.

So, save space on SSD and the term of life is increased. Ale, with whom, the speed of the robotic computer is significantly fast. Even more quickly, the disk reads or writes time files, documents, profile files, and the robot is more visible.

My categorical thought is that everything that goes to the OS and programs needs to be placed on an SSD drive. Working documents can also be saved to an SSD drive. On the HDD, you can save only a few tributes to the great obyagu - music, films. Otherwise, these data are rarely victorious - archives. In any case, you will take the most access to your SSD drive. Do not forget - the main reason for buying an SSD drive is speed! І means it is necessary to vychavlyuvati tsyu shvidkіst to the maximum.

Pardon a friend

Disk defragmentation. For the reason that the HDD disks have lost their way, people Defragment the SSD disk. Whose work is not necessary! The speed of access to more blocks of data from an SSD disk is approximately two orders of magnitude higher than in a single HDD. Therefore, the fragmentation of data is no longer visible on the speed of reading these data.

summary

Basic parameters of SSD disks

• Virobnik. Shorter SSD drive builders - Intel, Micron (Crucial), Samsung, Plextor, SanDisk, Toshiba, Corsair.
• disk capacity. The minimum size of the disk, which gives great speed of work and a good supply of free space for the continuation of the term of life is 240/256 gigabytes. The disks have a capacity of 60 - 128 GB, and the recording speed may be lower than 200 MB per second. We want other models of such disks with a speed of recording more than 200 Mb per second.
• controller. The best controllers for today are Marvell, Intel, Samsung.

Secondary parameters of SSD drives

• Memory type. SLC memory is "alive" for all, MLC і TLC, directly ubuvannya, the term life is less.
• memory process. Memory crystals created according to the technical process 19 or 20 nanometers may be the term of life less than the crystals created according to the technical process 25 nanometers.
• encryption hardware with support for the TCG Opal 2.0 and IEEE-1667 standard.
• Zakhist vіd vtrati eating.

Which SSD drive to choose

Roughly like this:

• Virobnik: Intel, Samsung, Plextor, Corsair, Micron (Crucial).
• Memory type: NAND Flash MLC or TLC.
• Disk size: pochinayuchi vіd 240 - 256 GB.

For example, such models: Intel 730, Intel S3500, Plextor M5 Pro, Crucial M550, Samsung 840 Pro. 3 models Samsung 840 Proі Crucial M550 to give a chance to write and read on this day. A disk Intel S3500 to give us a guarantee of integrity and the preservation of data.

Zvichayuchy the disk will need to be checked in the day before, so it will be checked on the computer. What is the best home or office computer on which the main work is the Internet and documents, as well as the found SSD disk with a capacity of 120/128 GB.

If it's a gaming computer, then it's better to take a minimum of 240/256 gigabytes, and in another way, pick up a shvidk_snu model. To the fact that one game takes up to ten gigabytes on a disk for an hour, and in the process of launching and in the process of playing, a lot of information is read from the disk.

As a computer for processing video, it will require more than 240/256 gigabytes and a model with the highest speed of subsequent recording and reading.

How critically important information will be saved and processed on the computer Intel S3500 or navit Intel S3700.

If the SSD is planned to be broken down from the old operating system, for example Windows XP, it is worth thinking about the effect of "degradation of the firmware" and about those how to get rid of it (report in the distribution).

Reminder of data

SSD disks have one shortfall in parity with HDD disks. In the event of a breakdown, data recovery from a "dead" SSD drive will be more foldable, and most of the time it will be impossible to recover.

Due to this fact, which is physical, data fragments are stored in different media and placed in different flash memory chips. Only the controller of the disk "knows" how to take it from the "porridge" of valid data. І vtrata part of the middle, especially quiet dezberіgaєtsya service information, can lead to impossibility of renewal of data.

There is one more peculiarity. It may not be possible to navigate to the correct SSD before downloading the files. If TRIM is enabled for the disk, then the controller will underestimate the data of remote files.

on the HDD drives Data from the removed files will not be deleted until the end of the day until you need a place for new files. I do not give you the opportunity to delete deleted files (do not always, but often).

So, take a look at the most common computer rule - it is necessary to make copies of important data. Tse rule, vtіm, vіdnositsya vzagalі to any type of disks, and not only to SSD. Whether the disc can die at any moment.

Update 2015 r_k

In rubles, SSDs have become more expensive and plus a big crisis - that's a nasty novelty.

The good news is that SSD drives have appeared with a 10-year guarantee - all these models Samsung series 850 pro. And Intel gives a 5-year warranty on its budget 535 series. Moreover, the smallest disks (120 GB) of these companies cost around 100 dollars.

Prices (dollars) are decreasing, productivity is increasing.

Tsіkava p'yatirka from the number of low-cost SSD disks, for the end of 2015 (from the Yulmart assortment) in order of price increase:

• Samsung 650 MZ-650120Z
• SanDisk Ultra II
• Samsung 850 EVO Series, MZ-75E120BW
• Intel 535, SSDSC2BW120H601
• Samsung 850 PRO Series, MZ-7KE128BW

Update 2016 r_k

The good news is that SSD disks, in which TLC memory is used, can be compared with disks on MLC memory.

It became possible to start the development of a new algorithm for understanding the signal from the middle memory - LDPC decoding. Today (in 2016) there are three controllers that support this algorithm:

• Samsung MGX, SSD drives Samsung EVO 750 and 850.
• Marvell 88SS1074, SSD drives Plextor M7V.
• Silicon Motion SM2256

Although the tests for durability to memory wear out, the Samsung EVO 850 and Plextor M7V drives show even different results. On a par with good discs from MLC memory.

That swidkіst roboti duzhe good. for example Plextor M7V 128 GB, on an Intel SATA 3 controller, gives a read speed of 497 Mb / s, and a write speed of 247 Mb / s (usually in the Plextool proprietary program). Aje Plextor M7V tse budget model, One of the found among all SSD drives in the middle of 2016.

A disk Samsung EVO 850(250 GB) given the speed (updated in Samsung's proprietary software):

• On SATA 2 controller (Intel ICH9): 268 MB/sec read and 250 MB/sec write. This security is confirmed by vimir in Ubuntu Linux.
• On SATA 3 controller (Intel): 540 MB/s read and 505 MB/s write.

On SATA 2, the speed practically runs into the limit of the SATA 2 standard itself. On SATA 3, the speed of reading also runs into the limit of the standard. І with whom Samsung gives 5 years of warranty for the disks of the line EVO 850. І to go out a borderline swedish and arched disk.

Update 2017 r_k

A lot of SSD disks in M.2 format appeared for sale, at prices similar to the 2.5 "SATA format.

However, it is necessary to clarify. Not all M.2 disks can be read and written significantly lower than SATA III, which means significantly lower than 570 MB per second. Є models, yakі, mayuchi format M.2, prote give svydkіst on the level of all SATA III.

The speed is closer to 1 Gb per second (or more) depending on the fact that the disk and the motherboard support the NVM Express technology.

Please check the specifications of your SSD drive and motherboard before purchasing. For NVMe support on the motherboard, not only the SATA III line, but also the PCI-e lines (2 or 4) are connected to the M.2 socket.

Axis, for butt, spear of motherboards with M.2 socket and NVMe support:

• ASUS H110M-A/M.2
• ASUS H170M-PLUS
• ASUS PRIME B250M-A
• ASUS B150-PRO

Firstly, for butt, SSD drives with NVMe support:

• Plextor M8Pe, PX-128M8PeG (N)
• Samsung EVO NVMe M.2

In addition, for supporting NVMe it is necessary to win a fresh version of the OS. Windows "out of the box" supports NVMe starting from version 8.1. For Windows 7, it is necessary to install an update and it is not trivial, since the driver needs to be integrated into the installation image. Microsoft has instructions. This topic has one more instruction, Russian mine.

On Linux, you need to tweak the kernel version 3.13 19 or more.

What is the choice of SSD drive with NVMe support? At the very least, on today's day, it is approximately twice as high as the speed of the robot, in parity with SATA III. And in the reading mode, the speed is already 3-4 times lower through SATA III.І this year, the development will increase. So, what is the sense of fooling around.

If you buy a new computer in 2017, then I will gladly take a motherboard and an SSD drive with NVMe support.

Solid-state accumulators (SSD) on the front of the big hard disks do not wash the internal rotten parts, and the stench is easier than the rest.
In addition, the stench is significantly better and more energy efficient than standard hard drives. So, those who dare to upgrade their PC, having installed a new SSD instead of an old hard drive, will increase the increase in speed in the speed of their robotic computer. Prices for solid-state accumulating materials vary in fallows in their capacities. The higher the SSD capacity, the higher the price. At the same time, it is necessary to upgrade the computer or the PS4 or Xbox One game consoles, or the best option is to save up at least 256 GB, but, more importantly, the bigger, the better. Well, now let's take a look at how many accumulated days are called the best SSD drives in 2017.

Sandisk Extreme Pro

One of the shortest solid-state storage devices in 2017 is the Sandisk Extreme Pro. This SSD drive is available with a memory capacity of 960 GB. Vіn pratsyuє dzhe svidko i reach svydkostі reading and recording up to 550 MB / s and 520 MB / s vіdpovіdno. Sandisk Extreme Pro is shock and vibration resistant. A 10-year guarantee is on the accumulator. Vіn goes like for a robot, so for a casual vikoristannya. Vіn miraculously works in case of any script vikoristannya.

Samsung 850 Pro SSD-storage, vzagalі, the pose of competition. This is one of the shortest solid-state accumulators in 2017. On the new one, a 10-year warranty is also expanding, while many other SSD-accumulators go with a three- or five-year warranty. This accumulative product is a premium-class product, rozrakhovanim on coristuvachіv s high vomogi to working navantazhen. The Samsung 850 Pro has unrefined productivity. Versions of the storage device Samsung 850 Pro with 256 GB of memory are available for sale at a price of 9,610 rubles.

The Samsung 850 EVO 500GB combines amazing productivity with brilliant features and smart pockets. This is the ideal SSD-storage for a gaming PC. Price hard drive Acceptable, and available in configurations with up to 2 TB of memory. Samsung 850 EVO takes third place in my shortlist crashing SSD discs 2017 rock. If you can't afford to use the Scandisk Extreme Pro, then I'm sorry that the Evo will be a great alternative, and wine, without further ado, is one of the best SSDs of 2017. Vіn є vіdmіnnoy zamіnoyu darling options to the very fact that, with its own average price of wine, it is not less pracyuє more good.

Crucial MX 200 offers high performance affordable price. The total speed of reading and writing is on the highest level (555 Mb / s and 500 Mb / s). Wine can also boast of encryption and temperature control systems. The temperature control system disables the possibility of overheating the building. Crucial MX 200 features Marvell 88SS9189 controller with critical custom operating system and Micron 16nm MLC NAND. The cache of the Crucial MX 200 is dynamic and changes according to data in storage. If NAND flash memory is launched in SLC mode, then the cache will change at the hour when data is written to the storage device. If you would like to spare, then the Crucial MX 200 will be right for you a good choice, Adzhe vin is one of the best accumulators of 2017.

The Korean company Hynix is ​​a great player in the flash storage market. So just like Samsung, stinks of using TLC NAND memory in their products. The type of disk controller is not yet known. The Hynix SL301 with a 250GB memory capacity is the most affordable hard disk drive available at a price, but it doesn't mean that it is far behind other hard drives in terms of productivity. The speed of reading / writing storage is 555 MB / s and 500 MB / s with the number of input-view operations per second in the range up to 95K and 85K per second. Hynix SL301 is one of the shortest SSD drives in 2017, and the 3-fold warranty is expanding further.

Rіzn_ SSD: what's the difference? Rick 2016

entry

As part of the material " Rіzn_ SSD: what's the difference?”, In which a few models of SSD and HDD of a different class were protested, we demonstrated on the butt of real coristuvalny operations that we demonstrated the intelligibility between these outbuildings. Since the moment of publication, mayzhe the second time has passed - the term behind the worlds of the computer industry of chimals. What has changed in an hour? Practically everything. Prices - send down. Assortment - having overwhelmed with vineyards mayzhe povnistyu, calling for a reduction in prices and the need for an adequate (new price policy) speed of production. Under the understanding of the "budget class" is now leaning on the configuration on TLC NAND, and to know in the cob rows of price lists in stores based on the memory of MLC NAND is a big problem. The class decision of the flagship level, that, like mi yogo, they bacheled the second fate of that - on the border of the world. Now, under the "flagship" solution, it is not a 2.5 "form factor with a SATA 6 Gb / s interface, but an M.2 form factor with a PCI-Express 3.0 x4 interface. A good example of this can be the low performance of Toshiba OCZ in the rest of the month: OCZ Vector 180 (2.5 "SATA) taken out of production, the flagship is now Toshiba OCZ RD400 (PCI-E 3.0 x4), OCZ Vertex 460A with 19 nm replacement memory on Vertex 500 (Toshiba OCZ VT500) on more cheap 15 nm memory, and in the lower price segment, the new Trion 150 is now incomprehensible (which has 480 GB of memory and more), and recently TL100 announcements, At the heart of which is an even more simple platform, lower Phison S10. Although it seems that earlier, the hackers made their way within the narrow framework of one type of MLC NAND memory and one form factor, then in 2016 the space for their maneuvers became larger, and the “crown in mass” of the PCI-Express 3.0 and NVMe interfaces was additionally expanded solution assortment. Ale chi є difference between them in practice? As a practical example of coristuvach, the situation with the work and the total entanglement of the current tensions and today is not a good sight. Zavdyaks to our permanent partners - the Regard store and the virobnik companies, we will renew the situation, having corrected different models accumulating among themselves.

Inspection and Testing SmartBuy Splash 120GB SSD (SB120GB-SPLH-25SAT3) Trademark SmartBuy continues to browse. Well, we recently protested SmartBuy S11-2280T, which has no analogues (there is only one solution on the Phison PS3111-S11 controller), and now one original accumulator has appeared in the assortment, which has taken the name SmartBuy Splash. And it is also based on an exotic controller - for the first time Marvell 88NV1120, which is not more common among the models presented to the domestic distribution of models.

Trohi suvoroї reality, Pіna marketing, otherwise the materiel needs to know

The race for extreme swede

“Boys, without an image, but I will understand why Russia is in a deaf place - through such experts, like you.”
The reaction of a koristuvach to the gladness of the participants in the forum does not magistrate
select a RAID array from two Samsung SM951 on LGA 1151.

I will give a quote on the basis of my special report. It’s a pity, it’s like this: people are guessing at miraculous constructions, absolutely not getting over the analysis of a technical story. Then, with various “shamanic dances”, the pragmatic “Frankenstein” is stunned, mingled with poignant and unfailing words about those who invent such an idea technically (not seeming about the financial side of food) and foolishness. And having thought up the construction to give signs of life, coristuvachi z podiv dnayutsya, that the result does not confirm their ochіkuvannyam and ... anew start the search for wine.

The same coristuvach used a "zero" level RAID array with two solid-state storage devices with a PCI-E 3.0 x4 interface on the motherboard, based on the Intel Z170 system logic set. The bottom line is that you want to install the SSD in the roses, connecting itself to the Intel Z170. Showing the block diagrams of this chipset will show the immaturity of the possibility of obtaining read speeds in the region of 4.2 GB / s (subsuming the possibilities of two SM951s on line operations).

On the right, the fact that the system logic itself is connected with the processor behind the third version of the Direct Media Interface (DMI) bus, as technically we can modify the combination of PCI-Express 3.0 lines with a bandwidth of 3.9 GB per second. Moreover, part of the throughput rate is set for the needs of the periphery - a truss controller, SATA- and USB-ports and others.

The only output in LGA 1151 is the installation of a microcircuit-switch of the PLX type, so that it connects to the CPU and the back of the line, but also pay through the cooperation of such an engineering solution is more expensive. Because of the numbers on the price lists, the stink actually already begins to change with the LGA 2011-v3 platform, there is no such problem simply because more PCI-Express lines (type 28 to 40, in the fallow type of the CPU model, against 16 for LGA 1151).

So why are virobniks installing two (or even more) roses of M.2 on system boards with processor socket LGA 1151? The reasoning is simple: it’s similarly suitable for separate exploitation of accumulators, if it’s only up to one SSD, and not all at once; to install other expansion cards (you can also add, for example, Wi-Fi adapters). No one has noticed the fact that such SSDs are used, as, for example, recently introduced by Intel SSD 600p, modification of a 128 GB volume provides only up to 770 MB / s for reading and 450 MB / s for writing. But, in the meantime, you can compare the Plextor M6e with two lines of the PCI-E interface (moreover, version 2.0).

Moreover, the Crimea is in vlasne navantazhennya іsnuє і so the titles of “service traffic”, which is always, as a result of which the real throughput of buildings is lower. And, as practice shows, in reality, LGA 1151 can achieve no more than 3.4-3.5 GB per second, which is practical in "laboratory minds" - with minimization of interference on all other elements of the system and accurate selection of the configuration of the test system. The most realistic ones seem to be 3.1-3.2 GB.

But one option for LGA 1151 systems is still є: install a PCI-E SSD in such a way that it will be connected to the processor and to the set of system logic. For whomever you want, there will be an available option for software selection by yourself operating system, But it's really unimportant for one simple reason: there are basically no RAID controllers on motherboards of the older class.

So, just like this: all operations on the "on-button" motherboards are driven by the driver on the software level with the resources of the central processor. A similar type of software arrays should be called unofficially called "FakeRAID". The right RAID controller includes the main microprocessor (mostly with thermal imaging), cache memory, a lantern for eating data in times of unscheduled power-up and a number of other wiring elements.

The total variability of such an add-on is higher, lower in most motherboards, not seeming already about the set of system logic itself, but to that model zrazok ASRock Z87 Extreme11/ac, De-installation LSI SAS 3008 and LSI SAS 3x24R purchased with flash memory, it is exclusive in its own way.

At the chase for a copy

The other half of 2015 - the beginning of 2016 was marked by the fact that the memory of TLC NAND has become a truly massive phenomenon in solid-state storage devices. Samsung has lost its "monopolies", moreover, two duets were practically seen to stand against one another: Toshiba memory with Phison controllers and SK Hynix memory with Silicon Motion controllers.

On the first duet, the bet was increased by more famous brandy on Kingston, Toshiba OCZ, Corsair and a number of others. Another in the solutions of larger-smaller popular brands appears only in the range of ADATA, everything else is the faceless Chinese and small houses in our (and not only in our) companies.

Recently, it entered the flash memory scene with a vertical, fragmented concern Micron and Intel (IMFT), in fact, there are more or less present on the market only one accumulator on it - the Crucial MX300, but, judging by the best, the arrangement has evolved in general do not change here - Toshiba western digital(SanDisk) prepare their 3D V-NAND.

Regardless of the obvious opposition, these platforms are similar both in terms of marketing warehouse and hardware ideology. Accumulating funds on their basis are positioned on given moment as a solution of the cob and middle equal, but the essence of the work is actually identical.

Despite the fact that TLC NAND can be less cooperative in its production, it will also have its own shortcomings. Zokrema tse dosit povіlna memory, and on the operations of the record її її shvidkodії do not show any criticism. So that such accumulators could still propagate the daily shows, zastosovuetsya cunning: part of the memory array is practiced in the “accelerated” recording mode (sometimes called “pseudoSLC”).

As a result, current models based on TLC NAND, with a slight vindication, being of a small obligation (~ 120-128 GB) carry in their official specifications the recording speed of approximately 400-550 MB / s - the very beginning of the SLC mode.

Ale obsjag danih, a kind of accumulating a building record on such a high speed, sound small and in staleness in a obligatory SSD can start with approximately 2 GB for the youngest modifications.

On the right, which is similar to the behavior already in no way is thrown into the eyes simply through those who copy effectively the great obligations of data - a situation that is blamed not so often. We do not know how to check the speed of copying a little on a par with old HDD models.

Persha "gathering" - Windows cache. Friend - SLC cache. The bottom “shelf” is the real speed of the Zenith R3 120 GB robot outside the SLC cache.

In fact, quite a real one more scenario, under which you can show a defective SLC buffer and low speed entries after him: installing igor with a great deal of borrowed space.

Vzagali, solid-state accumulators on TLC NAND most optimally look themselves in great commitments: and the resource is purely for accountability, it becomes transcendental, and the size of the SLC-buffer (which sound is set by SSDs) is great. That memory array itself is collected by such a number of NAND crystals that the speed of recording and the position of the SLC buffer grow to normal values. For example, the capacity of planar TLC NAND crystals manufactured by Toshiba, SK Hynix and Micron at once becomes 128 Gb, it’s clumsy to boost, that for an array of 128 GB you need 8 crystals, and an array of 512 GB is already accumulated with 32 crystals.

Before speech about the resource. There is only one outer stone of knowledge of materiel. In fact, in spite of the expansion of thoughts, the resource is shown not only as a numerical indicator (some of the data itself can be recorded on accumulating before the first battles), but also to save them. How is data saved from flash memory? The stench is saved in the middle at the sight of the charge, and it uses such a physical process, like a “flow of charge” into the middle of the court. The dead center of memory simply ceases to be read correctly. The stronger the wear of the elements of memory, the more active and faster the process. As soon as the recorded data can be read clearly, but after one hour problems will be fixed.

To improve this task, engineers are actively developing new algorithms for pardon correction, but only if the bar becomes indecipherable, otherwise it seems, “smitem”. At this moment, the microprogram of the controller can make a decision about overwriting some important data for “refreshing” the charge, but “breaking” the algorithms for “recovering the wear” with a great frequency of the change of the new middle, where the data will be transferred, the nitrochs will appear no better. And at some point in the world, the process of spending the middle charge will become just like an avalanche.

Key here: hour. In itself, there is a pardon of the most important tests for removal, which are carried out by different branches and more enthusiasts: only those recorded data can be read at a glance, but in a day's time (day, two, three) it can appear more, especially more worn . І in which the main folding is: the most correct test is three times over. It doesn’t seem like it’s about the classics of statistics, understand the “representativeness of the selection”: as a rule, one or two rounds are tested, and not a few different games. Otherwise, it seems, you can get stuck like on a copy of a flash memory with a random party, so on a storage, in a way, a batch of flash memory miraculously drank far away. Once again, it’s a reminder that if the “hour” is understood, it’s possible to remember the term, and not the sprat of days (like the Internet resources panicked). Nutrition terms reviewed in what material.

That same type of memory is still not great. Indeed, a non-abyaky injection into the resource of the hoarder is given by the specific features of several controllers and platforms in general. The most popular butt of the rest is the Silicon Motion SM2246XT controller. The new one has such power: it’s good to be only in that moment, if you want to accumulate 10% of your free time, otherwise WA will increase sharply (Write amplification, moreover, I’ve had a direct accumulation of WA ~ 1300) sensi vmiraє after a few months of operation. And the fact that MLC NAND (TLC does not support SM2246XT) is used in pairs with a sim controller does not get any easier. Then, the unloved bagatma of SandForce controllers, the implementations of data compression in them, in some minds (for example, with office robots) can secure their own advantage in resources in pairs with other controllers and flash memory.
