Technology of solid-state hard disks translated from English. SSD disk - what is it like: new horizons of data saving or worm marketing. Types of solid state hard drives

Nowadays, solid-state drives are increasingly being installed on computers and laptops. So what? SSD drive? To put it simply, this is a great flash drive, only one with more rapid writing and reading parameters. Solid state accumulators do not have any mechanical parts. It consists only of microcircuits. Hard drives have a high memory capacity, but little speed, and solid state drives with a low capacity have a speed that is much lower than that of a HDD.

features of the robot

Let's marvel at the work of HDD and SSD when copying or reading small files. The smaller the file volume, the greater the fluidity between the hard drive and the solid state.

Axis to realize what hard drive This is a notebook with any information. To know and compile this information, you need to dig through your notebook. And SSD is a great thing for paper, no matter what. You will definitely find more information.

The HDD spends quite a lot of time re-reading the heads, searching for the necessary sectors on the magnetic plates. The SSD simply shows that you need ready-made information. This is displayed when the system starts, when copying or reading thousands of other files (for example, photographs). That's why it's awesome this type The wear is dozens of times higher than that of the HDD. The program itself, installed on a solid-state drive, will run more quickly on the original hard drive.

It is best to buy SSDs from manufacturing companies that have a positive reputation for producing these products. These companies include Crucial, Kingston, Corsair, Samsung, Tohiba, Transcend, Intel, OCZ, SunDisk. It is not good to buy solid-state accumulators from Chinese brands or small-scale companies. These are the same: Apacer, Silicon Power, A-Data.

Since most SSDs have low memory consumption, but high productivity, they serve mainly for installing an operating system and programs on them, to increase their speed.

not enough

The main shortcomings of solid-state accumulators can be brought to their attention. SSDs cost a lot more than standard hard drives, and their prices fluctuate wildly.

SSD is a flash memory that consists of thousands of parts that may wear out. Basically, the depletion occurs during the hour when information is written to the disk. When reading the middle, you will come out of harmony much better. It is intellectually important that there is less capacity solid state accumulator, Tim is the most reliable, as he does not need additional microcircuits, and lives with less food. But it’s all in theory, and not proven.
Another shortcoming of the SSD is the inability to update data when deleted. If you suddenly have a power cut, then only a small circuit board in the hard disk will burn out, and the information that is lost on the magnetic plates can be restored. The solid state storage device goes out of tune with all the files that are on the new one.

pluses

Reading and writing speed is one of the most important parameters of an SSD. For solid-state accumulators, this fluidity ranges from 150 to 560 mb.s. A disk of average speed can have read speed and write speed between 450 MB.s. Hour of sufficient access Solid state storage devices are not insured, since they are more expensive than 0.1 - 0.2 m.s. SSDs are mounted on a SATA - 3 connector, so on motherboard, Bazhano is guilty of installing the same rose. Otherwise, the disk will not function to its full potential. Also, a solid-state drive is much smaller than a standard hard drive. He is not afraid of blows or blows
fall.

So why vibrati after all?

Now you see that SSDs are also hoarding. Let's wonder if they can be stagnant.

For office computer You can only install one hard drive with a size of 320 GB. If you play games, or you have a professional computer, then the best option is to install two disks. SSD size 60 - 128 GB. For installing programs, i operating system, and a hard drive of 1 - 2 TB. If you are purchasing a laptop as an addition to your main computer, you will be able to install a hard drive with a capacity of up to 500 GB on the new one. Since a laptop is the main computer, then it is better to use a new 750 GB HDD for everything - and more importantly, for what purposes it is used.

Almost every person already knows about solid-state accumulators, and people tend to profit from them. However, not everyone was wondering why disks are divided into one type and why SSDs better than HDD. Today we will recognize what the significance is and will conduct a small routine analysis.

The area of ​​stagnation of solid-state accumulators with skin rock is expanding. SSDs can be infected almost immediately, from laptops to servers. The reason for this is high fluidity and reliability. Well, let's talk about everything in order, so it's easy to see what the difference is between magnetic storage and solids.

Beyond the great principle, the main importance lies in the way of saving data. Thus, the HDD uses a magnetic method, so that data is written to the disk by magnetizing certain areas. With SSD, all information is recorded in a special type of memory, which is represented by microcircuits.

Features of HDD installation

If you look at the magnetic hard disk (MH) in the middle, it is a device that consists of several disks, read/write heads, and an electric drive that wraps the disks and moves the heads. To be honest, MZ is a lot like a vinyl record processor. Reading/writing speed of similar content current outbuildings can reach 60 to 100 MB/s (depending on the model and driver). And the wrapping fluidity of the discs usually varies from 5 to 7 thousand. Turns per wrap, and in some models the wrap speed reaches 10 thousand. Coming from a special structure, here you can see three major shortcomings and only two advantages over the SSD.

• Noise coming from electric motors and disc wrapping;
• The read and write speed is quite low, singing hour spend on positioning the heads;
• High incidence of mechanical breakdowns.

• The price for 1 GB is remarkably low;
• Great duty of saving data.

Features of SSD installation

The attachment of a solid-state accumulator in the root is differentiated from magnetic accumulators. There are all sorts of elements here, so there are no electric motors that move the heads and disks that turn them around. And all this is due to a completely new way of saving data. At this time, there are a few types of memory that are stored in the SSD. There are also two interfaces connecting to the computer - SATA and ePCI. For the SATA type, the read/write speed can reach up to 600 MB/s, while for the ePCI type it can range from 600 MB/s to 1 GB/s. SSD storage is required in the computer itself for more efficient reading and writing of information from the disk and back.

Due to its structure, SSD may have many more advantages over MZ, but there are some disadvantages.

• Visibility of noise;
• High read/write speed;
• Less susceptible to mechanical breakdowns.

• High price for 1 GB.

Just a little more polishing

Now that we have understood the main features of disks, let’s continue our current analysis further. The calls of SSD and MH also vary. Again, due to their characteristics, magnetic storage devices are much larger and thicker (which is not the case for laptops), while SSDs in size can be compared with hard drives for laptops. Also, solid-state accumulators produce several times less energy.

Summing up the pouch of our line, below is a table where you can see the capacity of the disks in numbers.

visnovok

Regardless of those, the SSD is practically better than the MZ in all respects, they have a couple of shortcomings. And itself, this is obligatory and virtuous. If we talk about storage, then at this time solid-state accumulators must be replaced by magnetic ones. Vartosta also has magnetic disks, which are even cheaper.

Well, now you know what the main responsibilities between different types If you are a hoarder, you will only have to decide which is simpler and more efficient to use - HDD or SSD.

I will try to explain this statistic to you, What is an SSD drive?, What is the importance of a standard hard drive, we understand about its advantages and shortcomings, and also you will know what parameters (criteria) you need to select an SSD drive when purchasing.

This article today about SSD storage devices did not come out of nowhere. It turned out that even a lot of readers have absolutely no idea what this is.

So, after describing the SSD life programs, the vast majority of business owners rushed to check their original hard drives with this program, which led to confusion in the comments. There I will write in more detail about SSD drives - vikonkuyu.

What is an SSD drive?

The “dry language” of the SSD disk sounds like this: solid state accumulator(SSD ,Solid-state drive) - a non-mechanical computer device based on memory chips.

It’s unlikely that you’ll have adopted the idea of ​​buying up your money. Now I’ll try to explain that the SSD drive is “wet with my fingers”, as it seems - on the fingers.

I'll come from afar... I'd like to ask you to guess (or find out for the first time) what a computer hard drive is (also called a hard drive).

Hard disk drive (HDD) is a device in your computer that saves all data (programs, movies, images, music... the operation itself Windows system) And it looks like this method is...

Information on the hard drive is written (and read) by reversing the magnetization of the cores on magnetic plates, which are wrapped in wild fluid. A special carriage is carried over the plates (and between them) like a rock, and is considered the head.

Everything on the right is jiggling and collapsing steadily. Moreover, even a “thin” device is afraid of causing simple fluctuations during the hour of its work, without seeming to be falling for a forgery, for example (the reading heads fit together with the wrapping disks and are saved on the disk).

And now the solid-state drive (SSD drive) enters the scene. These are the same devices for saving information, but they are primed not on magnetic disks, but on memory chips, as they said earlier. Such a big flash drive.

Nothing wrapping that collapses and jiggles! Plus - it’s simply divinely quick to write down/read the data!

Zliva - hard disk, right-handed - SSD disk.

Now is the time to talk about the advantages and disadvantages of SSD storage devices...

Advantages of SSD drives

1. Speed ​​of work

This is the fattest plus of many devices! Having replaced your old hard drive with a flash drive, you won’t recognize your computer!

Before the advent of SSD drives, the most convenient device in a computer was a hard drive. Win, with its long-standing technology from the last century, incredibly galvanized the enthusiasm of the fast processor and the secret RAM.

2. Noise level = 0 dB

It’s logical - there are no rusty details. In addition, these disks do not get hot during their operation, so the coolers are cooled down before they turn on and do not work so intensely (creating noise).

3. shock and vibration resistance

Having marveled at the video between connections and work, the SSD disk was shaken, thrown on the frame, knocked on the new one... and then continued to work calmly! No comments.

4. Mala vaga

This is not a great plus, of course, but still - hard drives are more important than their current competitors.

5. Low level of energy gained

I’ll skip the numbers - the battery life of my old laptop has increased by less than one year.

Few SSD drives

1. High quality

At the same time, and even more quickly, the prices for such accumulatives are steadily and sharply falling.

2. Reduced the number of rewrite cycles

The primary, average SSD drive based on flash memory with MLC technology is built to produce approximately 10,000 read/write cycles. And the more expensive type of SLC memory can already last 10 times longer (100,000 rewrite cycles).

For me, in both types of flash drives you can easily store at least 3 copies! This is just the average life cycle home computer, After any updating of the configuration, replacement of components with more modern, reliable and cheaper ones.

Progress does not stand still and the heads of the manufacturing companies have already come up with new technologies that will significantly increase the lifespan of SSD drives. For example, RAM SSD or FRAM technology, where the resource is desired and limited, is practically unattainable in real life(Up to 40 pages in continuous reading/writing mode).

3. Impossibility of updating deleted information

Deleted information from an SSD storage device cannot be updated every day. special utility. There are simply no such programs.

Just as with a large voltage drop in a typical hard drive, only the controller burns out in 80% of the cycles, then in SSD drives this controller is located on the board itself, together with the memory chips, and the entire storage burns out - Hello family photo album.

This concern has practically been reduced to zero in laptops and in the absence of an uninterrupted power supply.

Bus capacity

Remember, I am for you, how to vibrate a flash drive? So, when selecting a flash drive, the row-first axis is also important for the speed of reading/writing data. The greater the richness, the better it is. Just remember about the bus bandwidth of your computer, or rather, the motherboard.

If your laptop or desktop computer is already old, it’s obvious that an expensive and flexible SSD drive is not working. You just can’t tell half of your abilities.

To make it clearer, I will outline the throughput of different buses (data transfer interface):

IDE (PATA) - 1000 Mbit/s. This is a very ancient interface for connecting devices to the motherboard. To connect an SSD disk to such a bus, a special adapter is required. The sensitivity of the description of disks in this case is absolute zero.

SATA - 1,500 Mbit/s. It’s already more fun, but not so much anymore.

SATA2 - 3,000 Mbit/s. Widest on Danish moment about a bus. With such a tire, for example, my saver works at half his capacity. You need...

SATA3 - 6,000 Mbit/s. It's completely different on the right! The axis here is an SSD drive and show yourself in all its beauty.

So, before purchasing, find out what type of bus you have on your motherboard, as well as what the storage device itself supports, and make decisions about the worth of the purchase.

Axis, for example, how I chose (and how to choose) my HyperX 3K 120 GB. Reading speed is 555 MB/s, and data writing speed is 510 MB/s. This disk works in my laptop at exactly half of its capacity (SATA2), or exactly twice as much as a standard hard drive.

This year it will migrate to the children’s gaming computer, where it is SATA3, and it will demonstrate there all its power and all the flexibility of the work without streaming factors (older, more advanced data transfer interfaces).

Just a heads up: if you have a SATA2 bus on your computer and you don’t plan to install a disk in another (more demanding and daily) computer - buy a disk with a bandwidth of no more than 300 MB / s, which will be much cheaper and in the same hour twice as much as your cheap hard drive.

Form factor

Also, be respectful when choosing and purchasing a flash drive based on the form factor (size and dimensions). It can be 3.5 "(inches) - larger and slightly cheaper, but it won't fit into a laptop, or 2.5" - smaller and will fit into any laptop (for desktop computers Please be equipped with special adapters).

Therefore, it is more practical to buy a disk in the 2.5 "form factor - it can be installed somewhere convenient and sold (whatever) easier. This space takes up less system unit, That's why the cooling of every computer is growing.

IOPS display

The important factor is IOPS (the number of input/output operations per second), the greater the data shown, the faster the accumulation of files will be.

memory chip

Memory chips are divided into two main types: MLC and SLC. The versatility of SLC chips is much higher and the operating life is on average 10 times longer than that of MLC memory chips, but at correct operation, The term for storage service on MLC memory chips is to become at least 3 years old.

controller

This is the most important detail of SSD drives. The controller monitors the entire storage device, distributes data, monitors memory wear and distributes data evenly. I recommend that you give it the benefit of the doubt and the controllers SandForce, Intel, Indilinx, and Marvell have proven themselves well.

SSD memory storage

It’s best to use an SSD only to house the operating system, and save all your data (movies, music, etc.) on another hard drive. With this option, it is possible to buy a disk with a size of ~ 60 GB. In this way, you can greatly protect and eliminate the same speedy computer operations (and the term “accumulator service” will become more common).

Once again, I will bring to the fore my decision - special containers for hard disks It takes 2 hours to insert into a laptop instead of an optical CD drive (which I have tried a couple of times over the years). All you need is a wonderful solution - the old disk is in the place of the drive, and the new SSD is in the place of the standard hard drive. It would have been impossible to come up with a better idea.

And finally, a couple of quick facts:

Why is a hard drive often called a hard drive? Back in the early 1960s, IBM released one of the first hard drives with a design number of 30 - 30, which coincided with the designations of the popular Winchester drive (Winchester), the axis and the slang name to all hard drives.

SSD (Solid State Disk - solid state drive), Strictly apparent, it is not a disk. No SSD disks can be placed under the HDD, which saves information on magnetic disks. The data in them is stored on flash memory chips. From this comes most of the peculiarities of this type of hoarder. pros:

- SSD storage is much faster than HDD. Reading and writing speeds on solid-state drives on average reach 500 MB / s, and for the shortest HDD models they do not exceed 200 MB / s. Moreover, the advantage of SSD in speed increases significantly if you need to work not with just one file, but with countless others. The speed of a classic HDD drops tens of times - even Different files can be spread out on different sections of the disk and transferred to each new file, resulting in a new positioning of the recording head. The speed of an SSD does not drop so much when working with different files; V inherited SSD becomes larger than the HDD a hundred times!
- SSDs have durable parts, and are absolutely silent, and are substituted for the HDD. today hard disks, Of course, the noise is not as loud as their predecessors ten or twenty years ago, but all the same, when working, there is a noticeable noise and crunch.

- SSD storage devices are more resistant to stress, which is not safe for HDDs (the gap between the disk and the HDD head can be as small as 0.1 microns, and strong stress can lead to the disk head breaking, leading to data loss, or even to HDD failure). SSDs can calmly withstand shocks, shocks, and falls from low heights during operation.

Ale and disadvantages of SSD:
- high price. The price of 1 GB SSD storage devices is generally in the range of 25-50 rubles (although there are models ranging from 20 to 200 rubles per GB). For hard drives, this figure is 10 times lower - 3-6 rubles per GB. To put it simply, the average SSD is 8-9 times more expensive than the average HDD of the same capacity. At the same time, the development of flash memory technology is still growing and their prices are steadily falling: over 5 years, from 2012 to 2017, SSD storage devices fell in price by approximately 5 times. HDD drives over the same period, everything fell in price by 30%, so you can bet that even after five SDDs, accumulators will churn out as many as HDDs.
- exchanged number cycle recording. Flash memory chips suffer from resource consumption (especially in chips manufactured using TLC technology) and incorrect use of the SSD storage device can lead to failure. Do not use SSD drives for tasks related to partial write operations (saving timely files, swap files, cloud recordings, etc.). Do not allow SSD storage to suffer from data compression and defragmentation.

In summary, we can say that it may be optimal to choose an SSD in the back of a mobile external storage device, which is important for saving (audio video files, installation kits, ів и databases). In this case, the number of recording cycles is not so important, and resistance to mechanical infusions becomes an even more important advantage.

The high price of SSDs is causing great concern for cheaper models, but prices for them can be much lower than for other models that are similar in price and cost. Why?
First of all, the price may be less due to a different type of memory. The cheapest chips are produced using TLC technology, but they also have the lowest number of write cycles: 1000-5000. Today's most powerful SSD storage devices, MLC chips, are more expensive and on average require a resource of 10,000 write cycles. Roughly speaking, a cheap SSD storage device with TLC chips can last 10 times less than an expensive one with TLC chips.

Otherwise, although most SSD drives are equipped with a cache on DDR3 flash memory, in cheap models the cache can be daily. This changes the price, but also changes the fluidity of the work and the storage resource.
Thirdly, on cheap storage devices the generator can be protected and no food support capacitors must be installed. Since cache memory is used for storage, some of the data during operation is not written to disk, but is stored in caches. If your life is lost, your data may be irrevocably lost, so most SSD storage devices are equipped with storage support capacitors that accumulate an electrical charge sufficient to support the efficiency of the storage device at the hour of data transfer there are memories in the flash memory chips.
Fourthly, the price obviously depends on the brand. An accumulator with a name brand will cost more than a “nameless” analogue, and you don’t have to think about what you’re paying only for the label on the case. To value its reputation, the vibrator will now try to organize a reliable culture of vibrator production, which may be closely related to the vigor's vigor and reliability.

Upgrading SSD drives and flash drives.

The supply of USB flash drives is growing every month and is now reaching the same level as hard drives: for example, for 256 GB you can buy both an SSD storage device, a flash drive and a HDD. And, as everything is clear about HDD, then the choice between SDD and USB Flash is not so simple: the prices for them are approximately the same.
Fundamental differences between SDD and USB flash(form factor) no - both use the same technologies, the same interfaces (most importantly USB) and the same flash chips of several different types. The greatest flexibility lies in the fact that flash drives are not equipped with cache memory, so they can be played at the speed of SSD storage devices when working with anonymous files. If the storage device is being used for storage, an SSD with cache memory may be more effective. If the storage devices will be used for saving and transferring, for example, video recordings, then it would be more correct to include USB flash and SSD storage devices to one class of devices and select them based on the characteristics.

Characteristics of current SSD drives.

obsessed- the main characteristic of any hoarder, which ultimately means his price. When choosing an obligation for any accumulator, keep in mind what you should consider software security, So, as media files grow steadily, there is no way to stock up on stock; In addition, SSDs are storage devices, due to certain features of the organization of data recording, and do not require extensive filling of all available memory. On some SSD models, the recording speed can drop significantly when full, close to 100%.

Up to a storage capacity of 512 GB, larger SSD storage devices are more profitable: up to this point, the price per gigabyte decreases with the increase in storage capacity, as on a HDD. After this period, the price per gigabyte practically stops falling. In addition, under great circumstances, the price of SSD storage devices increases to significant numbers of tens of thousands of rubles.

interface Connecting an external SSD storage device must ensure the speed of data transfer is not less than the speed of reading / writing to the SSD itself.

interface USB 2.0 will ensure maximum data transfer speed of 480 MB / s, which is even close to the maximum speed of reading from an SSD, so with other equal parameters it is easier to transfer storage using a different interface.

USB 3.0 seems to be the optimal interface option for an external SSD storage device today:
- Its maximum transfer speed of 5 GB/s clearly exceeds the speed of the SSD storage device and does not affect data transfer from it;
- USB 3.0 is supported by more computers, laptops and tablets
- Due to the revolving capacity of USB, storage devices with a USB 3.0 interface can be connected to older computers, as long as the USB 3.0 ports are not damaged.

interface USB 3.1 provides a maximum data transfer speed of 10 GB/s, which is already excessive for SSD storage devices. Krim, when buying SSD-pico-pitchchers with the USB 3.1 iz izbaset, you will be at the well-being of those, a yak cable is equipped with an adherence: a basic basic equipment cable USB Type C, for Pidlochennya to the Zvichah-Rose USB TREVEN TROVHIID. And, although there are plenty of such adapters that support the USB 3.1 interface, SSD-storage devices are equipped with accessories, you can easily not find one at hand at the right time.

interface thunderbolt Having a wide expansion only on Apple computers, it will provide the highest speed of data transfer, but is absolutely incompatible with the USB interface. Therefore, choosing an external storage device with such an interface will be advisable, as long as you have to connect it to Apple technology. However, manufacturers understand that most devices with Thunderbolt support also support USB 3.0 / 3.1.

Appearing at the market shodo new technologies Saving data encourages food-free food for those who need food. What is SSD? Chi varto yogo put the place of the hard drive? So why is he so good that we can talk about him? Having read this article to the end, you will be informed of all the settings that will allow you to determine what you need to change on your computer.

Let's be clear: an SSD is a solid-state storage device, just like NAND memory, which does not require electrical equipment to save data. Essentially, an SSD is a flash drive that offers high speed for writing and reading information.

Upgrade from HDD

To draw parallels with a typical hard drive, you first need to delve a little into the theory and see how the HDD works.

HDD is a set of metal disks that are wrapped on a spindle. Information is recorded on the surface of the disks by a small mechanical head. Whenever you copy, create new file Or you start the program, the head collapses, preventing the recording from happening. To be precise, remove the vinyl cover - just replace the head with a mechanical head that reads.

Solid state accumulators do not damage any loose mechanical parts.

Other advantages of SSD:

• Shvidka reacts to the action of koristuvach.
• The robot is silent.
• Low level of consumed energy (less than HDD).
• Sustainability of overheating.

Here are the main advantages of solid-state accumulators, which koristuvach can “discover”. However, the power supply, which is better than HDD or SSD, will satisfy the needs of many consumers, so let’s equalize the characteristics of these two types of storage devices:

1. The fluidity of an SSD is higher, since the mechanical stage of locating the required space on the surface of the disk is known. The hour of access to data changes 100 times - the system installed on an SSD begins to literally fly around the same HDD.
2. The abundance of mechanical, roaming parts combines with the silent robots of hoarding and an increase in the triviality of one’s life. HDDs most often fail due to mechanical failure - SSDs do not have this problem.
3. The temperature of the SSD always stays at the optimal level, since it is not cooled with a cooler. The HDD overheats without cooling, which can lead to software and hardware problems.

Let’s be more objective: SSDs don’t have much. In the first place, the price is still high and it is completely unbearable. Another problem is the number of rewrite cycles. The HDD can be refilled with data and cleared as often as necessary; SSDs do have limitations, but in practice it is important to reach them.

All SSD storage devices have a service guarantee of 3-5 years, but they function much more, so it is not wise to focus on these numbers.

If you cannot choose between SSD and HDD, then the hybrid option is SSHD. Such accumulators combine the advantages of both technologies, however, the increased fluidity of the robot will only be noted when the operating system is important. Recording and reading of data will be carried out on the same level as with HDD, so such hybrids are not particularly popular among computer users.

Selection rules

So, you decided that it’s time to get rid of the old hard drive and install a solid-state drive in your computer - you’ve sorted out what you need and what advantages you have over HDD. However, another power issue is at fault here: how to choose an SSD?

Stores offer accumulators with different form factors, controllers and prices, so it’s important to find out what’s right for you as you go. To avoid feeling inconvenient when dealing with a consultant who suddenly wants to sell the SSD at a higher price, try choosing a storage device based on the parameters below.

obsessed

As has already been stated, one of the main disadvantages of SSD is the price, which is strictly tied to the obligation of accumulation. The minimum capacity as of today is 60 GB. Once you know that Windows 7 is installed, it contains 16-20 GB of space depending on the capacity, then it becomes clear that 60 GB is enough to install the system and a dozen programs necessary for operation.

If you want to store games and important graphics applications such as Corel or Photoshop on an SSD, then look at storage devices with a capacity of over 120 GB.

fluidity

Any hoarder (SSD is not to blame here) has two indicators of speed: writing and reading. The higher the value, the better, but remember that the characteristics indicate maximum fluidity. The real meaning can only be discovered in practice with help. special programs. If you have accumulated goods on the market for a long time, then on the Internet you can try to find some kind of liquidity test.

Interface and form factor

Most current SSD drives are in the 2.5 form factor with support for the SATA 3 interface. There may also be other, more expensive options:

• A PCI card is inserted directly into the motherboard slot.
• External SSD storage.
• Disk with mSATA interface for installation in laptops and compact computers.

What the interface needs: everything new SSD let out SATA interface 3, if you have an older controller installed on the motherboard (of the first or another generation), then you can still connect the accumulator. However, there is one caveat: transmission speed is assigned to the lowest values. If you connect SATA 3 to SATA 2, the bandwidth will be calculated based on the bandwidth of SATA 2.

HDD for computers has a 3.5-inch form factor, then for SSD installation 2.5 you will need a special adapter, which is often called a “sanchata”. It is a small frame made of metal that hangs on the disk installation site.

Before speaking, with the help of a special adapter you can install an SSD instead of a DVD in a laptop. It’s common to install non-corrosive drives and place a solid-state accumulator in its place, on which it is then installed operating system. A standard laptop hard drive is immediately cleaned and then stored as a collection of special files.

Memory and controller

There are three types of memory that contain a large number of bits of information in one space - SLC (1 bit), MLC (2 bits) and TLC (3 bits). The first type is outdated and is practically not victorious, so if you improve its characteristics, pass by such a hoarder.

MLC - the most expanded memory type at the moment, choose one. It has its shortcomings, but there is still no adequate alternative, since TLC is no longer starting to appear on the SSD market and is still very expensive.

The situation is similar with controllers: the most popular among processors and the widest range of computers use SandForce technology, which increases disk speed by compressing data before writing.

However, the SandForce controllers have one drawback, which can be appreciated by anyone: since the sensor accumulates information until it is stored, then after the liquidity is cleared, the record does not turn to the cob, so it becomes lower. However, the problem is simple: don’t fill the memory to the last byte, and you won’t lose speed.

Other, more expensive options: Intel, Indilinx, Marvell. If the budget allows, it is better to gain respect for solid-state accumulators with controllers from these companies.

Virobnik

The remaining parameter that deserves your respect is the vibrator. Of course, on various forums you can find a lot of posts about those that are better than choosing Kingston or, for example, Silicon Power, since they themselves specialize in the production of accumulators of various types.

However, this is not entirely true: there are fewer companies actually producing NAND flash memory than there are fewer brands on the market. Powerful vibration (and the result of development) looms:

• Intel.
• Samsung.
• SanDisk.
• Crucial.

The OCZ company, for example, until recently has had a lot of developments and has recently added a range of Indilinx controllers. Therefore, it is better to have respect for the given characteristics, and to keep the selection in the mind in the rest of the drawing.

Working with solid state accumulator

After your previous purchase and successful installation of the system on the SSD, turn on the computer and you will see that everything is working smoothly. To maintain such confidentiality longer, follow these simple rules for operating solid-state drives:

• Install a system that supports the TRIM command (Windows 7 and above, Mac OS X 10.6.6, Linux 2.6.33).
• Be careful not to overfill the disk - the recording speed will decrease and not be renewed (relevant for the SandForce controller).
• Save special files on HDD. Don't take away the hard drive you're working on - save your music, movies, photos and other data that you don't need access to at high speed.
• Use your RAM as much as possible and, if possible, avoid corrupting the swap file.

By following these simple rules, you will prolong the service life of your solid state accumulator and can avoid a sudden decrease in the fluidity of your machine.
