Which brand of ssd drive is better to choose? Which SSD is better to choose? Which SSD is faster

Does my laptop need an SSD?

Now solid state drive- is no longer a privilege of expensive laptops, but an almost obligatory component even of models costing 60 thousand rubles. However, if you ask yourself this question, then the most interesting things are yet to come.

As Confucius said: “Once you work on a computer with an SSD, there will be no turning back.” If in the last decade everyone was chasing hundreds and thousands of megahertz, then with the advent of SSD it became obvious that the bottleneck was the drive, not the processor.

If your laptop with a quad-core i7 takes a minute or more to load Windows and launch applications, the problem is definitely with the slow hard drive, and not with the processor. With an SSD, everything starts in a matter of seconds, files are opened and saved instantly. As a result, work becomes much more enjoyable. So let's be honest: the only time you don't need an SSD is if you already have one.

SSDs are expensive, aren't they?

Hard drives are still noticeably cheaper than SSDs based on the price of one megabyte, this is a fact. But in most cases, you don’t need a bulk “solid body”. You can always watch TV series online, store photos in the bottomless storage of Yandex.Disk, Google Drive or Dropbox, listen to music - from countless streaming services, domestic or foreign.

So it turns out that often users don’t actually have that much information on their laptop, and the basics can be stored on a fairly inexpensive SSD. True, on gaming laptop It's not so simple anymore. Of course, I would like to install all the toys on a solid-state machine so that the maps in Battlefield don’t take such a painfully long time to load. But, unfortunately, modern games They eat up too much space to be installed on inexpensive solid state machines. But there are options, described in the next paragraph.

Where will I store terabytes of photos from my last vacation in Tenerife?

And even if your laptop is filled to capacity with media files, this is still not a reason to refuse to purchase an SSD. Even a not very large volume is enough to install an operating system, browser and other essential programs. And then you won't recognize your laptop.

Moreover, it is not at all necessary to give up a hard drive with hundreds of gigabytes of goods acquired through back-breaking labor. Firstly, there are many laptops with space for both a fast solid-state drive and a large hard drive. Secondly, even if you have a super-thin ultrabook, this is not a problem - external hard drives have been on sale for a long time. And even hard drives with Wi-Fi for those who don’t like wires. Or again, you can rent a place in the cloud. Although, if you plan to use it as a balcony or a garage, that is, to look only once a year or less often and put everything there that you would hate to throw away, then it is better to take an external hard drive.

Can I install an SSD in my laptop?

In most cases, the answer is yes. It’s definitely not possible to install a “solid state” only in laptops in which it is already soldered directly to motherboard. But cases when the laptop already has an SSD are not of much interest to us in this material.

If you have only one slot for storage devices in your laptop, and it is already occupied hard drive, That best option- buy a solid-state drive to replace the hard drive, and for the hard drive, purchase a special container with an adapter to turn this hard drive into a convenient external hard drive. This way you solve the problem with both system speed and storing a large amount of data. And, in fact, you have nothing to lose.

One way or another, you will have to start by finding out how many drives you can install in your laptop and what type they are. There are not many variations, but enough to confuse the inexperienced person. Therefore, it is best to search forums on specific models, where people have already figured out which drives can be installed in a particular laptop model.

Which one to choose?

Form factor

The question of choosing a form factor depends not on you, but on your laptop. Older models only support 2.5-inch drives with a SATA interface. They are not as fast as some modern solid state devices with an M.2 connector. Most often, purchasing them is simply a necessity if the laptop does not have M.2.

However, the performance of a high-quality 2.5-inch solid-state drive is more than enough for everyday needs, and even more so for a person who has never dealt with an SSD before. Moreover, the M.2 connector itself is not an indicator of the drive’s performance, and among SSDs with M.2 there are even slower models.

However, the fastest M.2s are five times faster than standard 2.5-inch ones. But the point here is not even in the name of the connector, but in the data transfer interface. Faster SSDs are indicated by the acronym PCIe 3.0 (or NVMe), but we won't go into detail about such subtleties.

Volume

Anything less than 120 GB is not worth attention at all - nothing will fit there, and you will just experience constant pain. The exception is all sorts of Chromebooks with 32 and 64 GB drives, but often these are not even SSDs, but devices with slow memory and slow controllers that work even slower than hard drives.

You can already live with a 120 GB drive, but only on the condition that you really don’t store a lot of programs and files. Otherwise, it is better to pay attention to the 256 GB models.

Finally, 512 and 1024 GB are desirable figures for many, but the cost of such drives at retail is high, and the surcharge for modifying a laptop with similar ones is even higher. You can even put video games there, or, for example, two operating systems, each with its own set of programs and files, and much more that your imagination is capable of.

These days, SSD drives are becoming increasingly popular. They work much faster than the usual traditional HDDs, and their reliability and price are optimal for ordinary users. SSDs are used to store data in personal computers, laptops and even tablets.

But there are various manufacturers and various devices. It may be difficult for a novice user to choose required device. In this article, we have collected some tips on which SSD drive to choose in 2018, as well as an overview of the best devices.

Flash memory is replacing the fragile and bulky traditional disk everywhere. It's much easier to use a silent SSD that looks like a regular chip instead of one that spins at 100 revolutions per second hard drive. The second reason for replacement is greater speed SSD operation. Data will be read or written at speeds hundreds of times faster than on a magnetic hard drive.

SSD drives store data in non-volatile flash memory cells. You could say that this is RAM, which retains its contents after reboot. Thanks to high speed, the computer will respond to clicks much faster.

How to buy SSD?

As for the price, now SSD drives have become much more affordable. But when choosing, you need to pay attention not only to price, but also to speed and reliability. Three flash memory technologies are used to produce SSDs: SLC, MLC and TLC. SLT disks are more expensive, but the most reliable, one bit of information is written to one memory cell, MLC technology allows you to write two bits, it is cheaper, but does not last as long.

The next technology, TLC, is even cheaper and allows three bits of information to be written into one cell, but has an even shorter service life and even lower performance. The ideal solution would be MLC. You need to find a compromise between price, reliability and speed.

There are also several options for connecting SSD drives. Flash memory has a very high speed work, and increasingly the bottleneck is not the speed of working with memory, but the speed of the connection interface. Now M.2 PCIe type drives are gaining popularity; they provide maximum speed, but are still very expensive, so for most users the best solution will SSD connection via a SATA III interface, which is capable of delivering speeds up to 6 Gbit/s (or 750 MB/s).

In this article we will look at the best SSD drives of 2018 SATA type, since PCIe will still be very expensive for most users. If you are a laptop user, then you will also need to pay attention to the size of the SSD. All SSDs reviewed have a 2.5-inch form factor and a size of 69.9x100.1x7mm. Now let's move on to the list of the best SSD drives of 2018.

Conclusions

In this article we have reviewed the best ssd disk and 2018. There are cheaper, budget options, as well as expensive, but high-performance ones. Now you know which one ssd is better choose 2018 and if you were planning to upgrade your equipment, now you know what to do.

Let's start with the concept of form factor and interface. The “classic” for SSD is a traditional 2.5-inch hard drive enclosure with a SATA interface. Such SSDs are the most versatile - they can “invigorate” an old computer with SATA 2 ports, and achieve high performance from modern desktop and laptop hardware.

However, the capabilities of SSDs are much greater than what SATA allows. And here the confusion begins, because an SSD with an M.2 interface is, in fact, two different types drives - they can operate in SATA mode with the same speed restrictions (such compact drives in the form of expansion cards were originally used for laptops, but can also be installed in the corresponding slots on motherboards of stationary PCs), or they can directly use the PCI bus E x4 ( PCI-E interface NVMe) with much greater throughput- if you are going to purchase an SSD with an M.2 connector, immediately check in what mode it operates on your computer. For example, MacBook Air until 2012 they used M.2 SATA, and then began to work with M.2 PCI-E NVMe. Externally, they can be distinguished by the number of cutouts on the key: M.2 SATA has two, PCI-E NVMe has one.

However, there are also atypical M.2 SSDs on the market, designed for the PCI-E x2 interface and using the same two-cut key as M.2 SATA. They can easily work on motherboards with an M.2 connector that has both SATA and PCI-E lines, but on boards designed only for SATA-SSD they will be useless, although they are no different from M.2 SATA SSDs in appearance. Therefore, the type of supported SSDs must be taken into account.

And finally, there are SSDs that are installed in a standard PCI-E slot on desktop motherboards as ATX expansion cards - this is an option for those who need high speed, but there is no M.2 slot on the motherboard.

No SSD drive lasts forever - these are the features of flash memory, which allows only a limited number of write cycles. Therefore, naturally, it is best to choose a drive with a maximum TBW (Total Bytes Written) - but do not forget that they look pale compared to competitors Samsung SSD actually withstand a significantly greater number of recording cycles than stated in the passport.

The memory type determines and SSD resource, and its speed, and price. The cheapest drives use TLC or 3D-TLC, which can only last a little over a thousand write cycles. It is worth taking such an SSD with a decent reserve of capacity - it will provide sufficient resource. MLC memory is more expensive, but it allows you to rewrite a cell several thousand times. The most “tenacious” memory is SLC, which can withstand up to 100 thousand cycles, it is also the fastest... and the most expensive. A compromise option is an MLC SSD with SLC caching: the unallocated space there works as a high-speed cache, but such drives are sensitive to free space, and when it decreases below a critical point, their data exchange speed decreases.

As for the manufacturer, any SSD is a combination of several options for controllers and memory chips, so it is incorrect to compare brands: manufacturers that do not produce memory themselves will use the same chips as SSDs from leading manufacturers (Samsung, Micron/Intel, Toshiba , Hynix).

A solid-state drive is a new generation of storage devices whose operation is entirely based on memory chips, and eliminates the presence of mechanical parts. The first generation of SSD storage, which was based on flash memory technology, was in 1995, and was a huge success in scientific circles. Despite the fact that the stability of such a device left much to be desired and it was too early to consider it as a full-fledged alternative to HDD, a great future was predicted for it.

Since 2010, the computer hardware market has been replenished with SSD drive models with memory capacities from 64 to 512 GB, which marked the beginning of the gradual displacement of traditional hard drives. Compared to the latter, solid-state drives had a number of undeniable advantages:

• disproportionately high speed of writing and reading data, which has a positive effect on performance and performance;
• less noise and high resistance to mechanical damage due to the absence of mechanical parts;
• low energy consumption (in some cases up to 70%).

All this clearly indicates the possibility of a decent upgrade of hardware, especially for gaming needs.

To help you make your choice, we have compiled a rating of the ten best SSD drives from recognized market leaders. The selection of applicants was made according to the criteria of reliability, value for money, as well as based on reviews from users and recognized experts.

The best manufacturing companiesSSD- drives

Samsung. One of the most popular and trusted manufacturers of SSD drives on the global market. It has several lines of drives for computers of different levels. Budget and premium models, different form factors and maximum speeds.

Intel. The recognized leader in the field of computer electronics production did not ignore the development of SSD drives. Numerous experiments (including those from independent laboratories) have established the fact of the highest reliability of drives from this company, and partially justified the fact of their high cost.

Kingston. The arrival of this company on the market solid state SSD drives turned out to be very controversial and deserving of a portion of censure. The first samples of memory modules were purchased from Intel and relabeled trademark Chinese brand. After a short stint as a packager, Kingston established its own production and became a strong competitor to the flagship firms.

Transcend. A company whose main philosophy was to maintain a balance between the cost of products and their quality. As a manufacturer of SSD drives, it has firmly settled in the niche of the mid-price segment, providing users with, although not the most productive, but the most reliable devices data storage.

Plextor. A company from the Land of the Rising Sun that can withstand the competition of leaders thanks to the low price tag for its products. Despite the use of purely budget hardware in the manufacture of SSD drives (for example, Marvell controllers are combined with Toshiba’s not-so-top-end developments in the field of flash-memory), in terms of performance the latter are practically not inferior to mid-range models from the same Samsung and Intel.

Best external SSD drives

3 Transcend TS1TESD400K

Large memory capacity (1 TB)
Country: Taiwan
Average price: 31,500 ₽
Rating (2018): 4.6

An interesting model of a storage device, created in the best traditions of Transcend. The first thing that catches your eye is the excellent design of the disc case. But does the internal content of the model correspond to what is visible externally?

The answer to this question lies in the field of the concept “controversial”, and the reason for this is not the filling at all. The main problem with Transcend TS1TESD400K is a strange component USB cable 3.0, which constantly receives complaints from indignant users. Largely because of this, the SSD drive does not produce the declared write and read speeds (out of 380 and 410 MB/s, only 170 and 250 MB/s are realized, respectively, and in best case scenario). In addition, very often the data transfer process is interrupted due to the “disconnection” of the wire.

It is noteworthy that such problems can be avoided by the notorious replacement of the complete wire, after which the device (not always, but as a rule) continues to work without complaints.

2 ADATA SD700 256GB

Best Rugged Portable SSD
Country: China
Average price: 4,949 ₽е
Rating (2018): 4.7

The second line of the rating is occupied by a model that will clearly be of interest to photographers, videographers and others whose work involves processing a huge amount of information far from civilization. This is a protected device that can withstand shocks, falls, exposure to water and serious vibrations. Protection is provided by a housing made of durable plastic and a thick rubber rim. However, it is worth considering that there is no official compliance with any protection standards, and therefore hope for a miracle and use the SD700 in extreme conditions not worth it. Not recommended for use external drive and in the cold - the operating temperature range starts from +5 O C

Inside the black or light green case there can be 256, 512 or 1024 GB of memory hidden TLC type 3D NAND. The manufacturer claims read and write speeds of 420-440 Mbit/sec. These figures are confirmed by independent tests and user reviews. Data transfer is carried out via the USB 3.1 interface.

Since the invention of SSD drives, HDDs that have been proven over the years have gradually faded into the background. Despite their obsolescence, the latter still have significant advantages, but the superiority of new technologies turns out to be more significant. What are their advantages, and what parameters hide the disadvantages - we find out from the comparison table.

1 Samsung Portable SSD T5 250GB

The most modern. The best portable SSD for modern ultrabooks
Country: South Korea
Average price: 7,110 RUR
Rating (2018): 4.8

Sales statistics in recent years indicate that large desktop PCs are increasingly being replaced by portable laptops equipped with only the minimum required set of ports. Take, for example, the popular MacBooks - on their edges there was only room USB Type-C ports. External solid-state drives like the Samsung T5 were created to work with such devices. This is an extremely compact (57.3x10.5x74mm) and lightweight (only 51 g) model with a minimalist anodized aluminum body.

Samsung's proprietary V-NAND memory is installed inside. Models available with 250 GB, 500 GB, 1 TB, 2 TB. The declared read/write speed is good news - 540 MB/s. The disk is equipped USB port 3.1 Type-C. The kit includes two cables: Type-C to Type-C and Type-C to Type-A, which allows you to connect the drive to both modern and fairly old devices.

In conclusion, it is worth noting the accompanying software: there are applications for Mac, Windows, iOS and Android. They can be used to encrypt data using the AES 256 algorithm, update firmware, create backups data, etc.

The best SSD drives for a desktop computer

4 Intel SSDPED1D280GAX1

Fastest PCI-E SSD
Country: USA
Average price: RUB 29,864
Rating (2018): 4.6

Intel is one of the pioneers in the field of electronics. The company is best known for processors, but can also boast of some success in the field of storage systems. For example, the most fast SSD drives Optane family. Within this category, we will consider a couple of models at once. The first is a PCI-E card. The model is made in the “video card” format. Color – only black. The entire upper surface is covered with a massive heatsink that prevents overheating of the memory chips. The device looks stylish, is well assembled and gives the impression of a top-level device, which it is. The radiator, by the way, is not for beauty - during operation the card can heat up to 50 ° C.

Why does a solid-state drive with a capacity of only 240 GB cost 30 thousand rubles? It's all about flash memory technology. It uses Intel-developed 3D Xpoint memory, which has the best speeds and lowest latencies to date. In tests, the card produces about 2500 MB/s for reading, and 1700 MB/s for writing. Please note - not megabits, but megabytes per second!

3 Intel SSDPE21D480GAM3

The fastest 2.5' SSD drive
Country: USA
Average price: 44,850 RUR
Rating (2018): 4.7

The second representative of the Optane line is made in a completely different form factor - it is a 2.5-inch drive more familiar to most users. But two things immediately attract attention. The first is the case design. On it we can see many “pimples” and ribs that act as a radiator. You remember that these drives get very hot, right? The second is the connection type. The U.2 connector is used. It cannot be found on all motherboards, and therefore the manufacturer included an adapter for the more common M.2 in the kit.

There are practically no differences in technical characteristics - the bronze medalist only better withstands shaking and shock (withstands overloads of up to 1000 G), works at more high temperature(up to 85 degrees), yes, it consumes 12.8 W of energy, instead of 14 W for the previous participant. The remaining differences are in ease of use. Firstly, a 2.5 format disk does not take up space on the computer’s motherboard, and given the class of the device, it probably already has a massive, powerful video card. Secondly, the ability to “hot” swap the disk – you can’t do this with a PCI-E card. Thirdly, the cost/volume ratio.

2 Plextor PX-256M9PeY

Budget PCI-E drive
Country: China
Average price: 6,890 RUR
Rating (2018): 4.7

Let's move on from the exotic to more down-to-earth models, the cost of which corresponds to the capabilities of the majority of ordinary users of desktop computers. The device is made in the form factor of a PCI-E card. The design can be called cheerful, because in addition to a black heatsink and a small red insert, the case has RGB lighting. Gamers will definitely be pleased.

Inside there is TLC 3D NAND flash memory that supports NVMe and TRIM. Read and write speeds are stated at 3000 and 1000 MB/s, respectively. And to some extent, these indicators are true - files up to 3 GB will indeed be processed at maximum speed thanks to the fast cache. When working with large amounts of data, the speed will drop to “earthly” 500-520 Mb/s. Also note that the model from Plextor is the only one in the category that does not support encryption.

1 Samsung MZ-V7E250BW

Best price/performance ratio
Country: South Korea
Average price: 6,150 RUR
Rating (2018): 4.8

The leader of the rating is the long-proven SSD of the 970 Evo line from Samsung. This is the most affordable and most compact model in the category. The drive is installed in the M.2 connector, which means it takes up virtually no space in the case or on the motherboard. This allows you to install an SSD not only in a desktop PC, but also in a laptop. On the other hand, the form factor does not allow the installation of a cooling radiator, which is why temperatures are slightly higher than those of competitors - about 55 degrees.

The situation with speed indicators turned out to be extremely interesting - the 250 GB model lags significantly behind the 500 and 1000 GB modifications. For example, the sequential read speed is 2900 and 3500 MB/s for the younger and older models, respectively. When recording, the figures vary even more: 1000 and 3000 MB/s! Therefore, if performance is important to you, pay attention to a model with a minimum capacity of 500 GB. Finally, we note that the manufacturer provides a 5-year warranty on its products.

The best SSD drives for a laptop

3 Kingston SMS200S3/240G

The most reliable
Country: USA (made in China)
Average price: 4,240 RUR
Rating (2018): 4.7

The third position of Kingston SMS200S3/240G is due solely to the memory capacity of 240 GB, and does not hide any reproaches to the technical part. Built on the SandForce SF-2281 controller, the SSD uses the widespread MLC technology as flash memory - a multi-level information storage model.

As for the performance characteristics, in addition to 240 GB of memory, the speed of writing and reading information should be equal to 530 and 540 MB/s, respectively. The proven SATA is used as the connection interface, the maximum external data transfer speed of which reaches 600 Mb/s.

Particular attention should be paid to the reliability characteristics. MTBF is a decent 1 million hours – versions of SSD drives for desktop computers or premium for laptops. Combined with the cost, we get a high-quality drive model that can revive any weak system.

2 Western Digital WD GREEN PC SSD 240 GB

Best price
Country: USA
Average price: 2,965 RUR
Rating (2018): 4.7

Company Western Digital widely known for producing excellent hard drives. The leaders in the SSD drive market are completely different, but WD can also offer good options. One of them is WD Green with a capacity of 240 GB. This is a great option for those who want to speed up their laptop a little or replace a dying HDD with a more modern analogue. The main advantage of the model is its cost. For the silver medalist they ask only 3 thousand rubles.

You can't expect high performance speed for that kind of money. The model uses a SATA connection, which physically cannot provide speeds above 600 MB/s. Tests show sequential write and read speeds of 460 and 560 MB/s, respectively. Note that users in reviews complain about low speed reading 4K sectors. You can also find fault with the lack of TRIM, less time between failures than competitors, and much more. However, we remember the cost and stop paying attention to such trifles. In addition, not all laptops support NVMe, which means a solid-state drive via the good old SATA is a real salvation for them.

1 Samsung MZ-V7P1T0BW

The fastest SSD for laptops
Country: South Korea
Average price: RUB 28,390
Rating (2018): 4.9

In contrast to the previous participant, the top-end SSD M.2 drive is from Samsung. The cost and characteristics of the model directly indicate the scope of application - the drive is designed for the most powerful laptops. Uses proprietary memory V-NAND type and a Samsung Phoenix controller. Thanks to the connection via PCI-E (M.2 connector) and NVMe support, the model is capable of delivering speeds of about 2700 MB/s for writing, and 3500 MB/s for reading! At this speed, even 1 TB of disk space can be filled in less than half an hour. Among the nice features, we also note the power consumption of 5.8 W, which is very useful for laptop computers to save battery power.
