Samsung SSD 850 Evo review: Top performance for a low price

Editors’ note: This review was updated on July 6, 2015, when the 2TB capacity of the drive was released.

If you’ve been eyeing the Samsung SSD 850 Pro but can’t quite afford it, the 850 Evo is an excellent alternative. Actually, it may even be the better choice, especially since it’s the cheaper of the two, while still achieving fast — although not consistently as fast as the 850 Pro — performance.

Though officially an upgrade to the Samsung SSD 840 Evo, the new drive shares more in common with the higher-end 850 Pro. In my testing, the drive achieved impressively zippy speeds, especially in the performance-boosting RAPID mode. Also, I didn’t experience any bugs or installation issues.

There’s not much to complain about the drive except that its Samsung Magician software, which is required for RAPID mode and other features, is available only for Windows. That means other platforms, such as Mac, Linux or game consoles, won’t be able to take advantage of most of the drive’s features.

That said, with the current price of $65, $100, $165, $374 and $800 for 120GB, 250GB, 500GB, 1TB, and 2TB, respectively, the Samsung SSD 850 Evo is an easy recommendation for any home users who want to add a huge performance boost to their computer. (Note that cost of the 2TB is the suggested retail price, its street price will likely be lower.)

High endurance with 3D NAND

Following the 850 Pro, the 850 Evo is the second SSD from Samsung that uses a 3D vertical flash memory cell. Traditionally, 2D planar type NAND flash memory cells — the storage units on an SSD — lay flat on the surface of the silicon wafer. That’s common for most SSDs on the market. With the 850 Evo, the drive’s flash memory cells are stacked in up to 32 layers, which allows for significantly more cells in the same number of wafer bits. This greatly increases the density and means, among other things, more storage space for less cost.

Similar to the 850 Pro, Samsung also claims that the 3D NAND delivers very high endurance, which is the rating that quantifies the total amount of data that can be written to an SSD before the drive becomes unreliable.

Specifically, the 850 Evo’s 120GB and 250GB capacities have an endurance rating of 75TB. This means you can write 40GB per day to the drive every day, and it will last for at least 5 years. The 500GB, 1TB and 2TB capacities’ endurance is doubled (150TB) and will take even longer to run out.

Note that SSD’s endurance relates only to writing as reading doesn’t effect its life span at all. (For more on SSD’s endurance, check out this post.) Also, 40GB is a lot of data; in general usage, most days we don’t write even a fraction of that to our computer’s main drive. That said, chances are you’ll replace your computer a few times before the 850 Evo’s endurance is expired.

TurboWrite and RAPID mode

Similar to the case of the 840 Evo, the new 850 Evo supports TurboWrite technology. In a nutshell, TurboWrite enables the drive to operate a portion of its flash memory in a simulated high-performance mode of single-layer-cell flash memory, often found in expensive enterprise SSDs, as a buffer zone. During write operations, data from the host system is first transferred/written to this buffer zone at high speeds and then during the idle periods, the data is moved from the buffer to primary storage region. This results in much faster write performance from the user’s perspective.

TurboWrite Technology works within the drive automatically so you don’t need to enable it. You do need to manually enable RAPID, however, which Samsung first introduced in the 840 Pro.

RAPID stands for Real-time Accelerated Processing of I/O Data and it uses the available system memory (RAM) on the host computer as an input/output cache to boost the computer’s performance. Since most new computers come with a large quantity of RAM, RAPID is really a welcome feature.

To use RAPID on the 850 Evo, you’ll need to install Magician 4.5 (included on a CD, though you can also download it). The software supports the new RAPID version v.2.1 that now, according to Samsung, enhances error handling and fixes some compatibility issues. Once enabled, RAPID mode works by itself and automatically adjusts the amount of RAM it uses based on availability. Generally, RAPID mode uses up to 4GB of RAM or 25 percent of the host computer’s total system memory, whichever is less.

Other than that, you can use the Samsung Magician software to manage other features and settings of the drive. For example, you can use the software to enable or disable over-provisioning (a feature that uses part of an SSD’s storage space to enhance the drive’s performance) and encryption, as well as apply different settings that are optimized for the drive’s performance, endurance or reliability.

Affordable pricing

The 850 Evo is the cheapest Samsung SSD at launch with most capacities currently costing just slightly more than 30 cents per gigabyte. Even the latest 2TB capacity has the suggested price of just $800 (or 36 cents per gigabyte) and its street price will likely be lower. Overall, with this pricing and the great performance as detailed below, the new Samsung SSD 850 Evo is an excellent buy, and a better deal than its higher-end SSD 850 Pro.

Excellent performance

I tested the 850 Evo with a midrange computer running a Core i5 processor with 8GB of system memory, and it really made a big difference in the machine’s performance, even when compared to other SSDs.

In sequential data transferring test, which is a test that gauges the drive’s raw copy speed, the new drive scored a sustained speed of 183MBps when doing both writing and reading at the same time. When RAPID mode is turn on, it did much better, at 221MB/s. Overall, while very fast, compared to the SSD 850 Pro, however, the 850 Evo is still clearly behind.

Overall, the Evo’s performance is quite interesting. While its copy speed wasn’t the best, its application performance was great,topping the chart in certain tests when used an the RAPID mode. This means if you computer has a lot of system memory (8GB or more) the Evo is an ideal drive to get.


The new Samsung 850 Evo isn’t the fastest SSD on the market, especially in terms of copy speed, but in random access speed, which contributes to the overall performance of a computer, it’s neck to neck with the top-tier 850 Pro. And, like the Pro, it’s now also available in 2TB capacity.

So if you want to get the most value from your dollar, the Evo is clearly a better choice. Though its 5-year warranty time is short compared to the 10-year of the Pro, that’s still one of the longest on the market. And after using both drives for months now, I believe chances are you won’t need to use the warranty at all. On the other hand, if you want the top SSD with no compromises, the SSD 850 Pro is the way to go if money is not an issue.

All things considered, though, the Samsung SSD 850 Evo is for now the best deal for anyone looking to upgrade their computer to a super fast and reliable internal drive.

The Samsung 850 EVO is the latest in its affordable line of performance SSDs and shows Samsung’s desire to push the solid state game along, even at the lower end of the price/performance stack.

When it comes to solid state drives Samsung has really nailed its colours to the mast; it’s going to be first to market with new technologies, it’s going to aggressively drive pricing down and it’s going to do it all alone.

To that end, the Samsung 850 Pro was the first consumer SSD to show up with 3D stacked memory making up its various components. The Samsung 850 Evo does this as well, using a new spin of the V-NAND tech for its more affordable range of SSDs. And, when we say affordable, we mean it – it’s one of the most value-minded SSDs on the market today.

This new line of SSDs uses a new generation of 3D V-NAND that revolves around piling chips on top of each other, with ‘through silicon vias’ (TSV), which provides connections directly through the stack. This helps boost the bandwidth, as the connections are physically closer, but also means higher capacity drives are more affordable – they can be made without relying on the ever-shrinking of the NAND modules that make up SSDs.

This new generation of 3D V-NAND, then, has been designed to forge a path to higher capacity SSDs in the coming years. Samsung’s second-gen 3D V-NAND is made up of a full 32 layers stacked atop each other in every module. This means, the Samsung 850 Evo has a total density of 86Gbit.

  • Samsung 850 EVO 500GB (Black SSD) at Amazon for $29. 99


Now, that’s not the highest density NAND you’ll find in today’s drives — both Crucial and Intel are throwing out drives with 128Gbit density NAND in them and have partnered up to create their own 256Gbit 3D NAND for 2015 — but the difference is Samsung is only using 40nm silicon to get there.

Because of the celebrated shrinking of production processes in all spheres of computing — from processors to memory to graphics chips — it might at first seem like this is a backwards step.

We have, after all, become used to using 19nm NAND in our SSDs, even going as low as 16nm, so using a production process that’s more than twice as large would surely undo all the performance and efficiency boosts we picked up along the way down.

But because of 3D V-NAND’s ability to hit these high densities with such chunky lithography, combined with the bandwidth boosts of the TSVs inside the stacked modules, the larger dies don’t have any impact on relative performance.

The efficiency gains from previous production shrinks are also largely offset by the power reductions in the switch from 2D to 3D NAND.

Samsung estimates a 30% reduction in operational power with the Samsung 850 EVO compared with the older Samsung 840 EVO.

Hardy NAND

The 40nm process comes into its own though when we start talking about endurance.

The biggest benefit is the fact the larger production processes are more reliable and longer-lived than their smaller descendants. When you’re making the switch, as Samsung is, from the 2-bit multi-layer cell (MLC) design of its higher-end 850 Pro to the less-robust 3-bit MLC, any endurance boost is welcome.

Traditionally 3-bit MLC doesn’t last so long as the 2-bit kind, which is why you’ll see the Samsung 850 Pro rocking a full ten-year warranty.

With the 40nm 3-bit MLC of the Samsung 850 EVO it does have a shorter five-year warranty, but that’s still a good deal longer than the rest of the affordable SSD world with their three-year hedged bets.

    What is Samsung 850 Evo 2TB?

    Samsung leads the consumer solid state drive market by controlling every aspect of research, design and manufacturing of its drives. This advantage has been clearly demonstrated by its latest 850 series drives which offer excellent performance and value. The

    850 Evo was a more balanced version of the test 850 Pro, and now it’s supersized to be one of the largest SSDs we’ve ever seen.

    Samsung 850 Evo 2TB — Design

    Other than the huge features, little has changed in the design of the Evo. Key hardware is 3D V-NAND, which debuted in the 850 Pro. This is a simple manufacturing concept that has proven to work: the individual transistors that make up the memory chips are arranged vertically and horizontally.

    This relieves Samsung of the miniaturization pressure that previously governed SSD design, allowing larger transistors to be used to build chips. The end result is less power leakage and better performance, as there is no need to push tiny transistors into tiny spaces. A look at the manufacturing process illustrates the impact of 3D V-NAND — the transistors here use a more capacious 40nm manufacturing process, while traditionally built drives are based on 20nm processes or less. 9Samsung’s 0041

    3D V-NAND is used on the mid-range Evo drives and its high-end Pro products, but the 850 Evo’s price drops compared to using TLC memory chips. These chips are made up of three cells — each individual cell stores three bits of data — so fewer chips are required to produce the same capacity as the MLC cells in the 850 Pro, which only store two pieces of information in each cell.

    The Samsung MHX controller is similar to the previous chips of the company, but it is supported with additional memory, so it can work effectively with such a large capacity drive. Otherwise, everything works as usual: this controller is based on ARM technology, and the Evo drive has AES 256-bit encryption, TCG Opal 2.0 and Rapid Mode 2.0, which uses part of the PC’s memory as a cache for the SSD, so popular files can be accessed with more speed.

    850 Evo leaves the factory with 150 TB endurance. This is the same rating as the 500GB and 1TB versions of the Evo. And that’s decent — it matches the 850 Pro’s smaller drives. But when stacked against the 2TB 850 Pro, it fails; this drive is rated at a powerful 300 TB.

    SEE ALSO: Our verdict on the best M.2 SSDs

    Samsung 850 Evo 2TB performance

    2TB The 850 Evo didn’t fall short in our tests. The 512MB/s and 505MB/s AS SSD sequential read and write speeds are barely behind and slightly ahead of the 850 Pro, respectively. Evo also supports small file tests, and some of them are several megabytes faster.

    Its best performance was achieved in the 4K 64 write test, where 319MB/s was 8MB faster than the 850 Pro. It also proved to be several megabytes faster than the smaller 850 Evo we reviewed in early 2015.

    CrystalDiskMark didn’t have much choice between drives either. The 850 Evo and Pro recorded almost identical read and write results. When reading small files, the Evo was slightly faster, and when writing, it was only a couple of megabytes.

    It’s only slightly behind in Atto’s file read tests, but even so, its top speed of 559MB/s isn’t far from the limit of its SATA 3 port. In Atto’s file write tests, it was just as fast as the Pro. He, too, picked up speed quickly; even when dealing with tiny 8K files, read and write speeds are 432MB/s and 396MB/s.

    Our latest Iometer test evaluates performance over a longer period of time, and here the 850 Evo was impressive. Its total I/O figure is 5 961 was better than the 2TB Pro drive, and only a handful of smaller SSDs outperformed it.

    The 850 Evo showed no weaknesses in our tests — it matched or outperformed Samsung’s Pro version of the drive in several tests; it rarely fell behind. To get faster storage, you’ll have to sacrifice space for one of the smaller Pro drives or go beyond SATA with an M.2 drive or a PCI device like the expensive Intel SSD 750.

    Other things to consider

    This disc may cost a whopping £600, but don’t expect much in the box. The package does not include a 9.5 mm plug or screws. This, unfortunately, is the status quo in the current SSD market.

    The five year warranty is decent and on top of what is currently on the market. However, here is the 850 Pro winner; its reach spans an impressive ten years.

    Should I buy Samsung 850 Evo 2TB?

    There’s no denying that the 850 Evo is an impressive set, with solid performance supported by the largest SSD we’ve ever seen. However, there is no doubt that this drive is very expensive, which means that it is likely to remain a niche product.

    That said, it’s still tempting: it offers hard drive-style space with SSD-style speed, and it’s much more tempting than PCI Express and M. 2 drives, which have faster speeds but lower capacities.

    The £731 Samsung 850 Pro has a better endurance and warranty rating, but the 850 Evo matches the more expensive SSD in speed. If you’re one of the few who needs such a huge SSD, we’d go with the Evo.

    Not convinced by the expensive 850 Evo? Check out our latest component reviews or check out the mSATA and M.2 versions of this impressive drive.


    The 2TB version of the Samsung 850 Evo has superior storage capacity and is nearly as fast as the 850 Pro drive. If the best warranty and Pro endurance rating aren’t an issue for you, then this is an SSD.

    high-speed SSD review and test
    Just a couple of years ago, the company Samsung , in addition to the production of smartphones, TVs and other equipment, moved into the territory of computer components. very quickly won the love of users with quality and speed. And with its vast engineering and manufacturing resources, Samsung was the very first to be able to introduce NAND technology into its SSD production, achieving a significant reduction in their cost and performance improvement. This made it possible to attract a mass buyer, for which the company fought very zealously and desperately for almost 1.5 years after the start of production of SSD drives. And thanks to all this, the company’s solid state Samsung , today, is a kind of standard that is customary to be equal to, and that is why, today we will take a closer look and test the 9 series SSD0131 850 EVO Series 250 GB with innovative 3D V-NAND technology .

    Packaging and contents SSD Samsung 850 EVO Series 250GB

    With the release of the 850th series, the Samsung drives have changed the packaging design. Now they are decorated in a pronounced white color with the image and name of the SSD, as well as the logo of the company Samsung . In the kit, in addition to the SSD itself, which is located in a black plastic package, there is also a user manual, a disk with software and drivers for the SSD drive. Quite familiar and standard equipment, with the exception of a disk with proprietary software, which the company has Samsung is a calling card.

    Specification SSD Samsung 850 EVO

    The presented model of the SSD-drive EVO of the 850th series is equipped with 250GB of memory, which, as a rule, is more than enough for the installation and stable operation of the operating system, and the speed of reading and writing information is 540 and 520 Mb / s, respectively. The amount of memory presented in the drive should be enough not only for the OS, but also for all installed software and system drivers. In addition, 250GB should be enough to store multimedia files and even games. Usually, a regular hard drive is used for all this, but the 250 GB capacity opens up a little more space.

    The Samsung 850 EVO is based on the Samsung MGX (2-core ARM Cortex R4) high-speed controller, and the aforementioned 3D V-NAND technology. The controller is also equipped with a buffer memory chip LPDDR2-1066 with a capacity of 256 MB, which the device uses to store service data.

    Samsung 850 EVO Series The is equipped to capacity with a lot of technologies that are definitely worth talking about in more detail, because they are quite interesting and useful for the user, even though he does not directly use them. Before talking about the previously mentioned technology 3D V-NAND is worth a little more theory. The fact is that conventional memory (2D) is located in a flat structure, and in order to get even more capacity, for example, in a new series of drives, the manufacturer had to either increase the area of ​​the drive chip or reduce the manufacturing process on which the SSD is produced. Both actions led to high costs for the production of the drive, which would definitely lead to a significant increase in the price tag for it.

    Of course, no one benefits from a price increase: neither the manufacturer nor the buyer. However, the engineering and manufacturing resources of Samsung allow us to explore, experiment, operate and introduce new types of production, so the series of SSDs was created using 3D V-NAND technology, in which the memory is not located in one flat structure, like 2D memory, but in several planes of one structure. This structure looks like three-dimensional, that’s why it is called 3D. All this has significantly improved the performance and reliability of the company’s SSD drives Samsung , while not so significantly increase the price tag on them.

    This solid state drive also uses TurboWhite technology, thanks to which a small amount of memory is allocated for one bit per memory cell, and not three, as is implemented with other drives. Programming in SLC -single-bit cell mode is faster than in TLC -three-cell mode, so the speed of writing and reading data from the SSD is faster. Well, and finally, support for the well-known technology 9 has not disappeared.0131 Rapid Mode , when the information on the disk is first written to a special RAM (RAM) buffer of the computer, bypassing the SSD buffer, and only then transferred to the SSD via the SATA interface. The technology is not new, but it allows you to increase the speed of writing data to the drive, and is used in so many models, so it would be very strange not to see support for Rapid Mode and Samsung 850 EVO Series .

    Software SSD Samsung 850 EVO Series

    A feature of all SSDs sold under the brand Samsung is proprietary software that comes with the solid state drive. The software is called Samsung Magician. It provides the ability to view all important information about the SSD, including specifications and product serial number. In addition, using this program, you can find out about the condition of the drive, its wear, check the read-write speed of the SSD (overall performance), and also activate the data caching mode Rapid Mode and other supported technologies to increase performance. In general, the software is very useful and intuitive, besides, the software is accompanied by a good help system, which allows you to study in detail all aspects incomprehensible to the user.

    Test SSD Samsung 850 EVO Series

    Well, finally, let’s move on to the most interesting — to testing the performance of SSD Samsung 850 EVO Series

    Based on the results of the IOMeter benchmark, you can see that the SSD drive in sequential writing and reading loses both to its closest analogue, the Blast drive from the company Patriot with a capacity of 480 GB, and 850 PRO 500 GB. It is possible to escape a little only in sequential reading from its counterpart with an M.2 connection interface with a capacity of 500 GB. But in random writing and reading, our 850 EVO is significantly ahead of Patriot Blast . Random read and write rates are the same for both 850 EVO with SATA connection interface and 850 EVO with M.2 connection interface, but significantly less in speed than 850 PRO 500 GB. The results in the PCMark 7 benchmark are very similar to the random write and read results in the IOMeter benchmark. This is understandable, after all, the SSD drive 850 PRO is the older model, whose performance, and, accordingly, the price is much higher than that of model EVO .

    The Samsung 850 EVO Series attracts not so much with its performance as with its affordable price tag. The 250GB SSD version will cost a little more than similar drives of the same capacity, however, in the case of the 850 EVO Series, the user gets a fast and high-quality solid-state drive with support for interesting proprietary technologies and user-friendly software.
