An SSD is now becoming an invisible component of any modern gaming PC. The drivers of your OS and add-ons that are saved on SSD, Windows will be more profitable, and gamers will be more profitable. As soon as you try a hard drive, you will never want to turn to a mechanical hard drive. Luckily, SSDs are becoming great and cheap, so you can replace old hard disks to save terabytes of archives and media libraries.

In the rest of the hour, you will drink on the annex data storage based on NAND from smartphones and laptops, creating a marriage of NAND. It's a pity, as a result of the cost of the SSD for the rest of the month, it moved up. The price is similar to the DDR4 price line mill, but with the increase in 3D NAND production, the trend is due to change.

SSDs come in a variety of form factors, standard 2.5-inch SATA and larger new ones, which look like M.2 expansion cards. What a different PCIe interface, to get through the narrow SATA space, and in shorter models NVMe wins for a further increase in productivity, but stinks, as a rule, produce up to a large premium to the price. (True respect: also M.2 SATA drives, but don't worry, the shards still stink with SATA hardware). For Igor, we want good productivity, tightness and an adequate price.

The Samsung 850 Evo is still the flagship SATA medium, although some of the remaining NVMe alternatives, such as the Intel 600p, can beat it with some workloads. Our recommendation for budget SATA has also been updated after testing the Crucial MX300. This is not the best SATA drive, but it is one of the most found and first non-Samsung hard drives, which is the best 3D NAND.

shorter SSD

What does the term “shorter” mean, if the language is about an outbuilding, what should I remember? The best performance cost and efficiency, real-time productivity, or a glittering set of functions? The ideal SSD for a gaming PC is always the perfect balance of price / performance / reliability, and the Samsung 850 Evo SSD is worth it.

Samsung is the only manufacturer of solid-state storage devices that manages its vertical business, leading the way in manufacturing for the skin aspect of its products. We design the controller, program the firmware, convert the NAND flash memory and sell the finished product. Whether or not another company is afraid to rely on a third-party postal worker.

Perevagou є more tіsne spіvrobіtnitstvo between teams. When designing a controller, engineers need to know exactly what type of NAND they will work with. When writing the firmware, all the remaining details of the 850 Evo are left to the programmers. This allows you to customize such functions as TurboWrite, increasing both vibrancy and productivity.

The 850 Evo uses the same vertically stacked NAND flash as the 850 Pro. Such an arrangement ensures more high speed of the chip without the need to go along the path of rapid expansion of the middle, in order to start creating problems, like to add to productivity and hope. Samsung calls its patented 3D flash memory technology V-NAND and zoom stack 32 flash balls one-on-one (and the new V-NAND now has 48 balls). The leather ball is connected to the offensive one through the nameless crying darts, with a large number of z'ednan between the middle ones, below you can visualize the 2D (planar) scheme.

The 850 Evo is available in capacities of 120 GB, 250 GB, 500 GB, 1 TB, 2 TB and 4 TB. Not the most available SSD storage, but it's about 20 watts cheaper, the lower top Samsung SSD 850 Pro, and it's cheaper, the lower is the other SATA SSD storage, which can show some productivity. Imovirno, yoga is the best to call the average in terms of price, although in the rich tests of wines I will turn over more expensive disks.

Samsung estimates the recording capacity of the 850 Evo at 75 TB of five-year recording for 120 and 250 GB models, 150 TB for 500 GB and 1 TB models, and 300 TB for 2 TB and 4 TB drives. There are a lot of recordings, every day on average 41 GB, 82 GB or 164 GB for five years.

One more option SSD type Samsung is supplied in the kit software security to manage Magician. It's well-designed, with easy access to SMART information, a reference tool, and a function to protect your SSD (whatever you do). exciting disk USB). Win also includes the titles of Rapid Mode, which is part of your system memory dіє like a cache for an SSD, so if you write a file, you can write to the system memory with a speed, which means more than 4 GB / s, and then we'll drop it to the SSD for an hour of downtime. If the inclusions are switched on, part of your system memory is beaten, so it's the best way to beat, as long as 16 GB or more RAM is installed on your computer. Rapid Mode clearly looks in benchmarks, but in the real world it's less so.

It should be noted that if there are SATA SSDs on the right, performance in productivity is often an ice breaker. For example, in the PCMark 8 test, competing brandies are in the range of 0.1 seconds.

Smallest Budget SATA SSD

Accumulators Crucial MX300 SSD first followed Samsung in 3D NAND to SATA. At the same time, as Samsung can do all the advances in terms of advances and choices, Micron, the parent company of Crucial, is not easy, if you get to the right technology.

Instead of chasing after swedishness, hopelessly right now, if superficial technologies are being built to save the offensive generation, such as M.2 and U.2, Crucial will not replace the great mechanical hard disks, Yaki still vikoristovuyut more coristuvachiv for mass savings in old annexes.

Tse reasonable gra. Aje, for everything, for a lot of SATA SSD-storage storage devices, one type of one in terms of productivity is considered, and the real one is related to the price and available sizes. The MX300 was clear on its own mind, once it entered the solid-state storage market with the introductory 750GB model, it expanded to a new line with 1TB and 2TB sizes, as well as standard smaller options.

Last read speed 530 Mb/s, next write speed 510 Mb/s, last read speed 92,000 IOPS, last write speed 83,000 IOPS. Recording resource 160 TB, warranty term 3 years.

Productivity is remarkable, although it does not reach high scores in the 850 Evo benchmarks, but the variability of Samsung disks is about 50% higher, which can bring it up to $100 more. For a terabyte disk. Tsej rozriv zrostaє in the world zbіlshennya rozmіrіv diskіv.

Looking back at the vіdminnі pokaznіnі vіdіnі vіdіnіnі іnіnostі MX300, Crucial сає сає сає сає відміні відміні pribannyam.

Lowest Budget M.2 NVMe SSD

Crucial is not the only manufacturer in the SSD market that is Micron's newest 3D NAND. Intel has also jumped into the 600p M.2 storage spree and exploited the same strategy as Crucial's SATA MX300 storage.

In this way, Intel goes one step ahead and now upgrades SATA and mechanical hard drives, going right up to the next-generation M.2 NVMe interface to access these low-cost Micron 3D NAND memories. Might be more important for newer systems with empty M.2 slots, but don't mess around with smaller 600p models, as performance drops below 512GB.

Performance metrics Intel 600p 512 GB footprint: max. post-read speed 1775 MB / s, max. post-record speed 560 MB/s, max. speed of sufficient reading (blocks of 4 KB) 128,500 IOPS, max. 128,000 IOPS per record (blocks of 4 KB) Recording resource 288 TB and 5-year warranty. Intel 600p 512 GB can become compact, more swedish, and more cheaply replace SATA storage. And first of all, sell SATA storage devices, please keep in mind that most systems can only have one M.2 slot. And with SATA ports, there will be no such problem.

If you reach the igor on the right, you will great house in high-end Samsung drives, which dominate the upper part of the NVMe range. That's why 600p is the ideal NVMe SSD for gamers and the ideal way to load that expensive M.2 slot, besides the smaller, less expensive drive.

Shrinking high class SATA SSD

Samsung posіv first place in another category of the shortest solid-state storage devices and not without substations. The Samsung 850 Pro is the fastest SATA SSD you can buy for pennies. And with in-line migration to M.2 NVMe disks, it is unlikely that the throne will give up.

850 Pro wiish to 850 Evo and become the first SSD-capable V-NAND. Yak i 850 Evo, NAND flash memory becomes 40 nm, with 32 vertical balls. However, the fault is not based on TLC NAND: everything here is 2-bit MLC. That's why there is no need for SLC cache, because I give them a little bit of space formatted and three times better productivity in important recording scenarios. But the added value of V-NAND means a higher price difference, lower for other SSDs.
The 850 Pro has a tri-core MEX controller, which operates at 400 MHz, which is significantly faster than the dual-core MGX 850 Evo controller (if you want the 850 Evo models with a higher capacity, they also have a MEX). In tests, models with 512 GB and large capacities are three times faster and three times better for a higher price / capacity.

If you want the best SATA-capacity, then nothing can outrun the Samsung Pro 850, and at this stage, nothing is similar; possible highly productive solid-state storage devices - ce PCIe and NVMe. Ale chi really varto stained money on the SSD? Our recommendation, especially for engravings, is not.

In almost all real situations, there is no particular advantage over the Samsung 850 Pro compared to the cheaper SSD. Vіn koshtuє more richly, and і і pennies better spend on a larger video card, short processor or more system memory. Abo, let's say, on the SSD єmnistyu 1 TB replace 500 GB. The 850 Pro 256 GB is more expensive, the lower budget 480 GB SSD, and the 512 GB is more expensive, the lower budget 960 GB SSD.

If you choose the best possession and want to achieve optimal performance in any situation, and the price is not important, then invest pennies in an NVMe SSD. The only real benefit of the 850 Pro is the great tenfold warranty that comes with the 850 Pro. The capacity of 512 GB is allocated for 300 TB of records, or about 82 GB per day, every day, for ten years, which, insanely, is enough to record at work stations.

However, if you are looking for a professional solution, you probably don’t want to beat the Samsung 850 Pro for five years, not seeming already about ten, the shards of saving technology (and speed) look far beyond the scope of the essential SATA controllers. І long-term guarantee not renewed embedded files, Only a change of possession, so you need to save everything backup copy important files!

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 different “shamanic dances”, the pragmatic “Frankenstein” is chanted, intertwined 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 koristuvach was designed to select a "zero" level RAID array from two solid-state storage devices with a PCI-E 3.0 x4 interface on maternity pay, Based on Intel Z170 chipset. 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, in that the system logic itself is connected to 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 throughput 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. For the values ​​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 line (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

Another half of 2015 - the beginning of 2016 was marked by the time that TLC NAND became in memory solid-state storage devices truly a mass phenomenon. 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 not appear 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 wear, 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 do it 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 implementation 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.

ASUS GTX 1060 for 17 tr. to Citylink

If you need more system productivity, it is recommended to replace or add a hard magnetic disk (HDD) with a solid-state storage device (SSD) - or only such, as a kind of data transfer interface PCIe instead of SATA and, apparently, the NVMe protocol. The speed of data transmission in such an option for connecting flash memory is up to five times higher, and there are no technologies between the possibilities. In this time of day, the market is like a reminder of a superficial memory, however, it’s expensive to do it, and before the PC’s rulers, food will be given: and are you ready to stink for more swedishness for more pennies? Or better choose a classic one, but what about a more solid-state accumulator? Our test is guilty to ease your choice.

Accessories for the new era

Earlier, to replace hard drive on a PC, no need to think twice: the main rank was necessary to destroy, to change the classic HDD to a solid state drive (SSD). At the same time, the choice has become more important, even SATA at the same time with the AHCI (Advanced Host Controller Interface) interface protocol and expansion controllers for low-voltage magnetic storage devices. As a result, SATA 600 allows a transfer speed of up to 600 MB/s. With a CHIP rating, it has a lot of solid state storage with a SATA interface. So there is practically no reserve for increasing the speed when SATA is different.

In other words, the SATA interface is becoming a problem for flash memory, as the speed is constantly increasing. To that end, the new solid-state storage is not a SATA cable, but allows the use of a secure exchange of a PCIe interface, which is the type of connection traditionally used for video cards. Theoretically, the bandwidth of one bus line can reach 1 GB / s. Protested by us, we have accumulated up to a few lines, so - again theoretically - they can secure a total throughput of up to 4 GB / s. Ale, in the process of testing, such shvidkosts were not mined. The maximum performance reached by the Zotac Sonix Gaming Edition disk is 2613 MB / s. It’s richer, lower speed of a solid-state storage device with SATA support, but the possibility of an interface is not yet exhausted: in present moment the speed of the transfer is intermedium with a flash memory and a storage controller.

Two types of connection

On the view of SATA disks, when choosing a superficial solid-state storage device, it is necessary to take into account the capability of the motherboard and the form factor of the disk. They are sold in the form of PCIe expansion cards or in the form of memory modules that fit into the M.2 slot. Therefore, first you buy a memory, you need to change it, because there are roses on the motherboard, and if the motherboard is old, it’s clear that some kind of interface has a pink rose for data transfer, oscillators for the M.2 slot can but only vision of the SATA interface. If you are choosing a new PC, it is not particularly necessary for the drive to be turbulent: the Skylake microarchitecture may be affected by the presence of M.2 expansion slots and PCIe connectivity, as well as support for the new Non-Volatile Memory Express (NVMe) interface protocol, to a new stage.

Solid-state storage in PCIe boards seems to be of interest as an option for equipping old systems, which cannot be said about M.2 modules. In this way, next to change, on the motherboard, there is a slot for a video card, one more PCIe socket is available. Cream of that dry font on the boxes, there are also important ones: from six accumulators, they protested, which are represented by expansion cards, and only three are supported by PCIe 3.0. For example, Kingston HyperX Predator supports only PCIe 2.0, the maximum throughput of which is 500 MB / s per line. Irrespective of those speeds of reading and writing - 1400 and 1010 MB / s, it is significant to change the displays of devices from SATA, it is far from high-speed solid-state storage devices themselves. It is significant that PCIe 3.0 storage devices can be plugged into PCIe 2.0 slots, but in this way they can be connected. If you put a Kingston into a PCIe 3.0 slot, you won't get any extra speed.

SSD overheating speed drops

With current PCIe storage, data transfer speeds of over 2.5 GB/s can be considered. The throughput capacity of our test suite - Intel 750 - reaches 2513 MB / s. Approximately on the same level, Zotac is known, as well as Toshiba OCZ RD400 (2514 MB / s). The RD400 has a delivery option, in which an adapter is added to the M.2 module PCI Express, which allows you to insert your yoga directly into the PCIe slot. And, judging by the results of our experiments, it is entirely logical to win this over: we protested the module without an adapter and took away the results three times higher - when reading, the speed was 2382 MB / s, which is 130 MB / s less, lower with an adapter. On the right, the PCIe adapter can accommodate a heat-conducting pad, which allows more efficient heat transfer to the storage device. Option M.2 heats up more, that is why it is great, because through this the speed will decrease. Those that can show up much more strongly, demonstrate quite impressive results of the Samsung 950 Pro: the average reading speed of the accumulator added up to +1483 MB / s, moreover, it is blamed for health, reaching 2500 MB / s, but in the process it overheats, in the aftermath of which the speed is noticeably falling.

Tools for shaping for solid-state accumulators
A lot of selections of solid-state disks are tested by software, like analyzes like SATA, and NVMe-storage. For example, at Intel program called solid state DriveToolbox

OCZ RD400 (1,500,500 MB/s) is the leader in fast recording, followed by Intel 750 (1,339 MB/s) and Zotac (+1,249 MB/s). Samsung 950 Pro and Plextor M8Pe are significantly different from supernics according to these criteria. The speed of the 950 Pro was 1,143 MB/s, while the Plextor's results were the lowest at 828 MB/s. The Samsung disk, like and when reading, for an hour I write it down, suffers from overheating: it can be saved up more quickly, but if you win a big amount of air, it will overheat and lose heat. And the axis of the cause of the deplorable results of Plextor can be explained. The virobnik having equipped the accumulator with a wet radiator, which is not rich in appearance, according to all appearances. Navpakki: through those that the module is commencing, it doesn't work for all laptops. In the meantime, Plextor also offers a variant without a heatsink. Speaking about the problem of heating, we should take it to heart that our benchmarks are extremely addictive for accumulating, running scenarios, as in a routine robot, they are very rare. However, just in case you want to avoid overheating, you can add an adapter board, for example, Angelbird Wings PX1, equipped with a wet radiator.

Superficially short hour of vikonannya

High speed of transmission of data - it’s just wonderful Roboti Windows, The number of requests per read and write on blocks of data taken, counted per second (IOPS) can be greater, and the latency (average hour of playback when downloading to SSD) is low. The value of IOPS is an even more important parameter of a computer: which is more, it is better for systems, especially for quiet ones, which are constantly busy. In this case, the Intel 750 tested successfully, having seen more than 47,000 IOPS when writing, and more than 50,000 IOPS when reading. With an arsenal of 35,000 IOPS per read and write, Zotac is clearly the leader in testing. The RD400 and Samsung 950 Pro on record (44,000 IOPS) may lag behind Intel, but at the same time they are far behind the reading.

A gloomy picture for Kingston: Approximately 23,000 IOPS for reading and 17,800 for writing means the rest of the day is great. The reason for the main rank is in the old technology - the accumulator transmits data according to the AHCI protocol. The advantages of the new NVMe protocol are manifested first for everything in an effective massive parallelization of the task: the data transfer protocol sets up a support for up to 65,536 I / O queues with a depth of up to 65,536 commands per skin. The AHCI mechanism of enclosing one black deep 32 teams - but with great ambition, you can call for a collection of data.

Critical NVMe storage devices, for example, Samsung PM971, can be used in ultrabooks and tablets - their length is only two centimeters

The hour of reading flash memory of NVMe solid-state storage devices is practically reduced to zero: it takes less than 0.02 ms to read data from any Intel 750 element. Other test participants are not led by such opportunities. For an hour, access to them is between 0.03 and 0.05 ms. Alecim NVMe wins are not interchangeable. So, for NVMe, it will take a maximum of two years to register, AHCI - up to nine. In addition, NVMe supports the work of modern rich-nuclear systems, although AHCI manages to do it badly with a new set of kernels.

The price of a high-capacity gigabyte

In Denmark, the food about those that are cheaper - SATA or PCIe - is unambiguously blamed on SATA. For example, one gigabyte of the top-end solid-state storage device Samsung 850 Evo can hold 1 TB for a total of 20.4 rubles. Approximately one gigabyte of Kingston HyperX Savage with a nominal capacity of 480 GB: with a fixed storage rate of 11,200 rubles, one gigabyte costs approximately 23.3 rubles. And the price of one gigabyte of the Intel 750 protested by us is three times higher. And yet, new super-storage storage devices are already heading for lower prices: for example, Plextor M8Pe, the most accessible solid-state storage device with NVMe support, is the best choice - it is not more expensive than SATA storage devices. New NVMe accumulators are also reviewed by the term of service: they contain flash memory of the MLC type (Multi Level Cell - the middle of the dekilcom equals) with a remarkably high rewriting resource.

Promising PCIe and NVMe

PCIe instead of SATA, NVMe instead of AHCI - this is how the formula looks like today for success, which guarantees record-breaking speed for robotic solid-state drives. You can navigate to mobile outbuildings. However, first of all, buy a new SSD, change your mind about the platform, and also prepare to make a big sum. If you're offended, you'll be swayed, as a whole you can get a solid-state storage device Intel 750 with a high speed of data exchange and a higher IOPS, which will improve our rating. Since there is no room for a PCIe card on your platform, you can use the Toshiba OCZ RD400 in the M.2 form factor. In the case of Samsung and Plextor storage devices, in the RD400 robot, problems with overheating turned out to be small. The way to the new era of solid-state accumulating waters.

More and more koristuvachiv nabuvayut SSD disks for installation in a PC. The stench vikoristovuyutsya in parallel with the HDD or replace them. Solid hoarders may have a lot of advantages in pairs with hard disks. It is necessary for him to know how to select an SSD drive for the computer correctly.

What are you?

A solid accumulator is a non-machine device for collecting information. It is recommended for installation on PCs, laptops, servers and if you need to replace HDDs. SSDs are built on the basis of memory chips, which are controlled by a special controller.

Advantages and shortcomings

advantages:

• high speed of reading / recording data and productivity of work;
• low heat generation and reduced electricity;
• there is no noise through the presence of roaring details;
• small dimensions;
• high resistance to mechanical failures (up to 1500g), magnetic fields, temperature differences;
• stability to the hour of reading data independently from memory fragmentation.

shortfalls:

• the number of rewriting cycles has been reduced (1,000 - 100,000 times);
• high quality;
• defense against electric shocks;
• Risk of re-using information without the possibility of renewal.

Head characteristics

When you buy an SSD for installation on a computer, pay attention to its main characteristics.

When buying SSD drive in pershu cherga to give respect to obsyag and victorious victories. If you buy a tablet for installing the OS, choose an attachment with a memory capacity of 60 GB and more.

Modern gamers will be able to install the game on a solid-state storage device to increase productivity. If you are one of them, then you will need the option with 120 GB of memory.

How do you buy a solid-state accumulator replacement? hard drive, Get out of the rozrahunka, what kind of information is collected on the computer. But in this case, the capacity of the SSD disk is not to blame, but less than 250 GB.

Important! Vartist of a solid-state accumulator without intermediary to lie down in obedience. So, depending on your budget, use the SSD to install the operating system, and the HDD to save data.

Most of the current SSD models are sold in the 2.5-inch form factor and are packaged in a box. Through chains, the stinks are similar to classic hard disks of the same size.

Korisno know! To install a 2.5-inch SSD drive in a standard 3.5-inch hard drive in the middle of the PC case, special adapters are used. For some models of cases, the transfer sockets have a form factor of 2.5 inches.

1.8-inch and smaller solid-state accumulators are on the market, like vicorous in compact outbuildings.

connection interface

Solid-state accumulators may have a few options for connection interfaces:

• SATA II;
• SATA III;
• PCIe;
• mSATA;
• PCIe+M.2.

The widest option is the connection for an additional SATA socket. SATA II models are still on the market. The stench is no longer relevant, but you should add such an attachment, the zavdyaks of the totality to the SATA interface will work with the motherboard, which supports SATA III.

If you choose a solid-state storage device with a PCIe interface, you may need to install drivers, and the speed of data transfer will be better if you use SATA connections.

The mSATA models are designed for compact attachments, but follow the same principle as the standard SATA interface.

Models M.2 or NGFF (Next Generation Form Factor) are the continuation of the development of the mSATA line. The stench may have smaller dimensions and great possibilities for compiling digital technology with the help of assemblers.

Speed ​​of reading / writing

Chim tsey higher, more productive computer. Average indicators of speed:

• reading 450-550 Mb / s;
• write 350-550 Mb/s.

Virobniks can be not factual, but the maximum speed of reading / writing. To find out the real numbers, take a look on the Internet and look at the models that have shown up.

Krim tsgogo, zvernіt respect for an hour access. Tse hour, for which disk you need to know the program or OS information. The standard indicator is 10-19 ms. Ale, shards of solid-state accumulating parts are not ruhomy parts, which is significantly more swedish, lower hard drives.

Type of memory and hour of work until the end

Є kіlka types vykoristovuvannyh in SSD disks in the middle of the memory:

• MLC (Multi Level Cell);
• SLC (Single Level Cell);
• TLC (Three Level Cell);
• 3D V-NAND.

MLC is the widest type, which allows you to save two bits of information in one middle. Vіn may not be a great resource for rewriting cycles (3,000 - 5,000), but there is less co-operation, for which reason this type is stagnant for mass production of solid-state accumulators.

SLC-type saves only one bit of data in one com- merce. Digital microcircuits last for a trivial hour of life (up to 100,000 rewriting cycles), high speed of data transmission, and a minimum hour of access. Ale, through great variety and small efforts to save data, the stench is victorious for server and industrial decisions.

The TLC type saves three data bits. Headache - low variability. Medium short: the number of rewriting cycles is 1,000 - 5,000 repetitions, and the speed of reading / writing is lower than the first two types of microcircuits.

Korisno! In the remaining hour, the recorders were able to increase the lifetime of TLC disks by up to 3,000 rewriting cycles.

3D V-NAND models replace standard MLC or TLC chips with 32-ball flash memory. The microchip has a trivi- mer structure, which is why it is necessary to record data on one area much more. With this, the reliability of information storage increases by 2-10 times.

Vіd vіrobnik to lay down the nadіynіst of the work of the solid-state accumulator. Eminent companies let out new additions with advanced technical and hardware support. At their factories, there is a high level of vimogi, which ensures the quality of the products that are produced.

Current SSD drives manufacturers: Samsung, OCZ (Toshiba), Kingston, Crucial, Corsair, Plextor, GOODRAM, Silicon Power, Transcend.

TRIM function

The most important add-on function for a solid-state storage device is TRIM (collection of information). Vaughn polegaє in the offensive.

The information on the SSD is written down in the mailbox. If the disk is writing data to the client, as it was previously victorious, it will be cleared from the beginning (on the HDD window, where data is recorded over the actual information). If the model does not support TRIM, it clears the middle without interruption before writing new information, through which the speed of the operation falls.

As a solid-state storage device, TRIM supports TRIM, and it takes the OS command to delete data in the middle and clear it not before overwriting, but for an hour of “idle” disk. Robe in background mode. Tse pіdtrimuє shvidkіst record on designated virobnik equal.

Important! The TRIM function is the responsibility of the operating system.

attached area

Tsya region is inaccessible to koristuvachevі and vikoristovuєst zamіst polmanih seredkіv. In yakіsnih solid-state accumulating vaults, it will be up to 30% in obligatory attachment. Ale deyaki virobniki, schob reduce the compatibility of the SSD drive, change up to 10%, zbіlshyuchi themselves obsjag shovischa available koristuvachevі.

Zvorotniy beck of a medal of such an approach is due to the fact that the region is awarded with the TRIM function. However, it’s not very big, it’s not possible to use it for background transfer of data, due to which, with equal “engagement” of the SSD, 80-90% recording speed is sharply falling.
