256gb ssd | Choosing the best 256 gb Ssd for drive for computer and laptop

Looking for the best 256gb SSd the Samsung 850 Evo SSD 256 or 512 gigabytes is still the best choice for most people. It’s fast, reliable, comes with a long warranty, and comes with proprietary software to make it easy to switch from a regular drive to an SSD.

256 gb ssd Guide:

September 2019 Update : Last year Samsung released an update to all of its Evo 860 and 860 Pro SSDs , moving their production to new memory (64-layer TLC 3D V-NAND) and a new controller. However, from the point of view of the average user, the characteristics of the SSD have hardly changed, in some places even slightly worse. Nevertheless, the price of the new SSDs remains the same, but the old models are simply sold out until they run out. Therefore, you can safely buy both the old and the new model. However, it’s important to keep in mind that the new 860 series no longer has a 120GB SSD. Therefore, if you need just such an SSD, you should hurry up with the purchase. Because how to produce such SSDs?

And now about this in more detail.

Why should you trust me?

As I mentioned in the description of the site, I have been writing about technology for the last ten years or more. I spend even more time with this technique. This means that almost every day I try something new, adjust something, reconfigure, change, and so on in the same spirit. This text is a summary of my (and not only my, but also my colleagues’) experience. So yes, you can trust me.

Who needs an SSD?

If your computer or laptop is 3 to 5 years old (earlier models may contain SATA-II connectors, in which case the purchase should be considered separately, see the corresponding section below), and your system is based on a regular hard disk, then it makes sense to think about buying an SSD. The dollar is pretty high right now, so you should have a good reason to buy it.

What does an SSD give? As a rule, it has three main advantages: almost instantaneous loading of the operating system (less than 10 seconds), faster loading of files and programs, and lower power consumption (the latter is relevant for laptops and allows them to work longer on battery life).

Thus, if the work of your computer is limited by the performance of the disk system, the purchase of an SSD is more than justified. With it, the system will simply “fly” and live much longer on battery power

The picture above shows an example of just such a case. There are two bottlenecks in this laptop – the power of the integrated video card (you can’t do anything here) and the performance of the hard drive. The processor and memory are in complete order. After installing the SSD, the system will become noticeably faster.

Who doesn’t need an SSD?

July 27, 2016 Patch: There  is a regular controversy in the comments about whether an SSD can be used to download torrents. Since opinions differ, let’s listen to the manufacturers themselves. In a recent post on the Geektimes website (an iron project that broke away from the legendary Habrahabr), SSD manufacturer Kingston directly writes :

But to download torrents, if there is something to choose from, it is better after all to the hard disk. Because there are SUVs for fun and there are SUVs for driving in the mud. Here HDD is more likely to belong to the second category.

Those. everything is simple, if the SSD is the only disk in the system, then download it. You still have no choice. Moreover, this is a truly magical sight – to watch how the download speed does not rest against the capabilities of the hard disk, and reaches enormous values. But if you still have a hard disk in the system, then it is better to write torrents there. Because the SSD resource is not rubber, and regular download-delete-download still reduces it.

How much SSD storage should you choose?

For desktop computers, the minimum comfortable volume is 256 GB. It makes no sense to take less for two reasons:

  1. Typically, 128GB models operate at noticeably slower write and read speeds.
  2. In order for an SSD to work for a long time and reliably, at least 30% of free space must remain on it. This is due to the fact that the disk controller must evenly distribute the load between the memory cells for its even wear.

Thus, 256 GB is the minimum SSD storage for a desktop computer. A traditional hard drive can be used to store files that do not require daily access (see infographic on HDD selection ).

With a laptop, things are a little more complicated. Since many laptops do not allow you to put both an SSD drive and a hard drive at the same time, the entire amount of information will have to be stored on the SSD. Therefore, 512 GB is the optimal solution that will suit most users. Alas, the price of such a disk turns out to be impressive, but on the other hand, you get quick access to all files and noticeable battery savings. By the way, if your laptop for some reason has a DVD-ROM, you can dismantle it (this is done very simply) and replace it with a hard drive bay. In this case, you can put an SSD in place of the standard disk, and connect an old disk instead of a DVD. Thus, you will speed up the system and increase the place.

Does it make sense to buy a SATA-2 SSD?

Judging by the comments, this point should be discussed separately. So, if your motherboard supports SATA3, then the interface bandwidth is 6 Gb / s, SATA2 – only 3 Gb / s. Those. it would seem a twofold difference. However, as we said in the section on flash drives, it is not the linear speed that is important, but the speed of reading scattered files. Because when booting, the system collects the OS in separate files, smeared all over the drive at random.

In order to answer the question whether it is necessary to install a modern SSD in a system with SATA2, let’s turn to a thorough article from the THG.RU resource. The authors sequentially connected the Samsung 840 PRO drive, by the way, an excellent SSD of the previous generation, to the SATA2 and 3. To have something to compare with, the third in the test was the very fast WD VelociRaptor hard drive. If you look at the graph of linear read and write speeds, the advantage of SATA 3 is more than noticeable.

Please note – in this case, the HDD practically does not lag behind the SSD connected via SATA-2. However, as we understand it, linear write and read speed is not that important. In a real situation, we are more interested in the speed of an arbitrary (random sector). Let’s see how disks behave with a random sector size of 512 Kb.


As you can see, the difference is also twofold, while the hard drive starts to lag far behind. If we make the sector size in 4Kb, then the difference between SATA will practically disappear, but the HDD will generally become very slow. What does this lead to? To the fact that, say, loading your operating system from an HDD will take noticeably longer than from an SSD. Moreover, the difference in connection will not play a role. Windows will boot up almost equally quickly.


What conclusion can be drawn? Everything is very simple – if you use an SSD exclusively as a boot and system one, there will not be much difference between SATA-2 and SATA-3. Both interfaces allow it to load quickly enough. And the purchase of an SSD is justified even in this case. Moreover, it is the purchase of an SSD that can revive your old laptop, making it work at a very good level.

And here’s the fun part: if you have an old computer with only SATA-2, then you hardly need a modern high-speed SSD. You don’t have a problem with him. Yes, the system will boot noticeably faster. But the performance itself … Let’s just say that for this money it is easier to buy additional memory and upgrade the motherboard and processor. The difference will be noticeable even on an old HDD. But if you have reached the bottleneck in terms of hard drive performance, and you do not want to spend money on a significant upgrade, then yes, you can look at the purchase. But, again, it’s better to think about upgrading your computer, and then go here and choose a modern SSD that will 100% unleash the potential of your system.

Which SSD should you choose?

At the moment, this is the beginning of 2020, the best choice would be to buy a Samsung 860 EVO SSD of the size you need. At the start of sales, it was quite expensive, but now prices in dollars have dropped slightly and the price has become more or less acceptable.

Why 860 EVO? The point is that most modern user-grade SSDs have similar specifications. Trust me, if you are not an SSD specialist, then in most cases you will not notice the difference in performance between different models. Between the hard drive and the SSD, notice a significant one. But between different SSD models – no.

Then what comes to the fore if not speed? These are price, reliability, the ability to survive a large number of write cycles, the quality of the controller, the quality of the firmware and proprietary software that makes life easier for the user.

In this respect, the Samsung 860 EVO has practically no competitors at the moment.

  • It is relatively inexpensive (at the time of publication, an average of 8 thousand for a volume of 256 GB and 12 thousand for 500 GB);
  • it is fast (on average 516 Mb / s for reading and 426 Mb / s for writing);
  • it is reliable (Samsung itself is the manufacturer of both memory and controller);
  • it can pump up to 150 Tb of data through itself (this is a very large amount of data for most users);
  • it has a 5-year warranty.

In addition, if you are using Windows, then the bundle includes proprietary software that allows, firstly, it is convenient to migrate from a hard drive to an SSD, and secondly, and this is the most pleasant thing, to use up to 4 GB of RAM as a cache for the disk. This makes working with the disc even faster.

Another plus for the purchase can be the presence of hardware data encryption. Most users do not need this at all, but for some it may be critical.

And if there is no noticeable difference in speed, is there something cheaper?

If the price of the Samsung 860 EVO seems too expensive for you, then I would put the Crucial BX100 in second place.

In fact, for a slightly lower price, you get a slightly lower warranty – only three years, less data that can be pumped through the disk (72 TB instead of 150 for Samsung, although this value is enough for the eyes). Also, it doesn’t have the same software bundled as the 860 EVO. But no one bothers you to use third-party programs, of which there are quite a few. You just have to tinker a bit with the setup.

So, if that doesn’t scare you, the Crucial BX100 is a great alternative to the 860 EVO. Moreover, Crucial BX100 consumes less energy and the laptop will live with it at least a little bit, but longer (about 10 minutes).


Despite the fact that M.2 slots appear in more and more laptops, motherboards, and a) can be faster than a regular SSD, b) they allow you to use both SSD for Windows and HDD for storing files at the same time, it is very difficult to advise something here … The fact is that at the moment there are two varieties of the M.2 standard. These are M.2 SATA and M.2 PCIe. Each of them is divided into several more sub-standards depending on the physical size, and M.2 PCI, in addition, is also divided into several sub-standards depending on the number of PCI lanes connected.

Those. you can’t just go to a store and buy an M.2 disc there. First you need to study the documentation of your laptop or motherboard, understand which of the standards suits you, and only then buy something specific. Therefore, I repeat, it is very difficult to advise something specific here. If you are still determined to buy an M.2 SSD, I advise you to go to this page of

 our website, where we tried to collect the most complete information on the compatibility of various drives with various hardware. And already based on the data received, select a specific model.

If you have M.2 SATA of 2280 sizes, then you can not philosophize and take the same Samsung 850 EVO in M.2 format. In all other cases, you will have to look carefully.

SSD for professionals

If your job involves processing a lot of raw RAW photos, or you are constantly editing large volumes of video, working with 3D graphics, a fan of daily heavy torrents, or running multiple virtual machines at the same time, then a regular SSD is not for you. In this case, I would pay attention to the Samsung 860 Pro version.

Why is it better. First, it’s faster. This is actually noticeable when working with large files in random read mode. In normal operation, the difference is not noticeable, but in the case of professional use, the difference can be felt. Secondly, it has a 10-year warranty. Thirdly, it was originally designed for such a tough operating mode and has the corresponding reliability. In fact, it has no competitors in its class. The price, unfortunately, is also 30% higher: 256 gigabytes cost 10-11 thousand rubles, 500 GB – about 16 thousand.

Who else loves the Samsung Evo SSD?

The portal 3Dnews.ru recently completed a large test with a 256 gigabyte SSD. The results were summarized in a graph showing performance versus price.

As you can see, the Samsung 850 EVO is the best price / performance choice. Several quotes from the reviewers:

  • Samsung 860 PRO . It is the most productive and most technologically advanced SATA SSD, based on the unique 3D MLC V-NAND. In addition to outstanding performance, this model also stands out for its high reliability, which is backed by a 10-year warranty. In addition, the Samsung 850 PRO boasts a whole bunch of different nice little things, such as support for OS-managed encryption and an excellent tool utility.
  • Samsung 860 EVO . The younger brother of the invincible 850 PRO also stands out from the competition. Yes, it is based on TLC V-NAND and therefore gives a lower performance during write operations, but this does not prevent it from remaining one of the best SSDs in terms of weighted average performance and occupying a leading position in the mid-price category. In addition, the 850 EVO inherits from the 850 PRO the entire proprietary set of additional advantages: encryption support, high-quality software, and more.
