Review: Samsung SSD 860 EVO M.2 (2280) SATA3 500GB [MZ-N6E500BW]

Samsung 860 EVO is the world’s best-selling SATA SSD. Specially designed for mainstream PCs and laptops, using V-NAND technology and a reliable controller with a streamlined algorithm, this drive is a very fast SSD for everyday tasks.

The EVO series uses 3-bit flash memory per cell (TLC), but it reserves 2.3% of the NAND capacity for background operations and caching. This helps offset the poor write performance of the TLC memory.

Samsung has equipped the 860 series SSD with a new MJX controller that supports low-power DDR4 memory, so it probably has a new built-in memory controller. Most likely, the company managed to create an MJX controller based on a smaller lithography, which ensures lower power consumption, cooler operation and lower production costs.

Samsung approves that its fourth-generation 64-layer V-NAND consumes 30% more power than its 48-layer predecessor. Samsung has taken a big step forward by lowering the input voltage from 3.3 V to just 2.5 Volts. It also allowed to reduce the data access speed to 500 microseconds, which is 1.5 times faster than in the previous generation.

The 860 Series supports hardware encryption using Opal TCG and Microsoft eDrive.

The 860 EVO has excellent endurance and reliability. If there weren’t a new 860 Pro that provides double endurance rating, the 860 EVO would become the market leader in solid state drives with 150 TB endurance for recording for every 250 GB of used capacity. SSDs are still covered by the standard five-year warranty.

Today we’ll take a look at the new 860 EVO SSD to see how Samsung has improved the world’s best-selling solid state drive. The Samsung EVO series is so popular in some countries that it sells better than all the other SSDs combined! Samsung uses the proven formula in the new EVO series in the new drive. Samsung changes the price when competitors begin to pose a threat to the company’s sales, and the company always launches a faster model when disks from other manufacturers become too productive!

Many people think that Samsung Pro 800 models are the best SATA SSDs you can buy for money. They work best with robust workloads because 2-bit per cell (MLC) flash is more reliable than TLC. But MLC is redundant for most consumer workloads, which tend to be short-lived. The EVO series is well suited to consumer workloads because it often provides higher write speeds than the Pro series, but this high level of performance lasts only for a short time.

The 860 EVO is similar to all other EVOs released after the 840 series. That was when Samsung switched to a black case and abandoned the dark gray color scheme. Outside, it’s simple, but Samsung does not need to improve a proven design or even change a methodology. The EVO series comes without any new features, and this formula works as long as the 860 can stay one step ahead.

The 860 EVO also has three different form factors. The full power range comes in 2.5 “, while the M.2 2280 (SATA) scales to 2 TB and the mSATA model reaches 1 TB. Samsung and Mushkin are the only two SSD manufacturers to announce the new mSATA SSDs in recent years. Most companies have shifted their focus to M.2 SSDs and largely ignore the outdated mSATA interface.

Samsung lists identical performance specifications for each 860 EVO capacity. Consistent performance is 550/520 MB / s read / write bandwidth, while arbitrary performance reaches 98,000 / 90,000 read / write I / O. You will need to actively use intensive multitasking programs to achieve this level.

Samsung’s advantage over the rest of the market lies in its ability to deliver superior performance with low queue depth. Samsung had it before 3D memory, but it got even better when the company launched the production of drives with V-NAND. More troubling for other SSD makers, Samsung’s continued momentum with each revision of V-NAND makes it difficult for competitors to pinpoint a performance benchmark. V-NAND is now in its fourth generation, and Samsung has once again raised the bar for performance and endurance, further reducing power consumption.

Customer reviews

Buyers noted the convenience of a form factor suitable for even the most compact system assemblies, which only houses the motherboard and low-profile cooler .. The advantages of the drive include its energy efficiency – the temperature even under load does not exceed 35-45 degrees. Also, users were attracted by the five-year warranty from the manufacturer and the durability of Samsung solid-state drives, time-tested. Other important advantages of SSDs: speed, performance, ease of installation even in compact cases.

Installing a disk into a computer takes 3-5 minutes: took it out of the box, inserted it into the slot, fixed it with a small screw (comes with the motherboard / or is located in the motherboard itself).

People also like the Samsung Magician application, thanks to which they can update the firmware, optimize and even speed up SSD.

The main disadvantages that buyers noted are not the most advanced memory chips used in the drive – TLC and cost compared to another companies products.

As other negative aspects, buyers noted a significant drop in speed when they reached the used volume on the disk of 400 GB of / 500 GB. Also, users in their reviews note that for the price 30% more expensive you can find options that are 5-6 times faster with the same volume.

Some buyers complained of poor compatibility with a fairly large number of motherboards. It is recommended that before buying, read the list of compatible SSD devices on the website of the manufacturer of your motherboard.

Conclusions: For office tasks, this model seems to be a good option, many times faster than the HDD and probably more reliable than its counterparts.

Capacity: 1 TBStyle: Single
I just built my new gaming PC and am using this as my primary drive. I bought the 1 tb model and installed it and was puzzled why it only showed me having 230 gb available after installing windows. I used disk clean up and still the same available space. When I pulled up the hardware configuration it showed it to be a 256 gb drive and not a 1 Tb drive. I downloaded Samsung Magician which conformed that the drive I installed was in fact a 256 gb drive and not 1 tb. The packaging was sealed and intact and even the wording on the drive itself says 1Tb but in reality it is a 256 GB drive. I then checked the serial numbers on the drive and the box and they do not match up. So, ensure you get what you pay for.

Negative review from Amazon buyer


New and Snappy Product from an Old, Reliable Lineage
January 28, 2018 [Verified Purchase]
Capacity: 500 GB Style: Single
Already converted the 2.5-inch drive in my HP Envy 17 to a Samsung 850 EVO 1TB drive and saw the M.2 slot and thought it would be interesting to try something new. Then Amazon brought out the 860 EVO M.2 500gb ssd and I just couldn’t resist. I have to say immediately that the installation hardware-wise is just like all the M.2 installs on YouTube, etc. Plug in at 30-degree angle with the five-contact side of the drive on the right with the sticker side up. Didn’t come with a mounting screw, but I ordered a box with some in it (M2x3 with 4mm-4.5mm head I have been told.) M2x3 with
4.5mm and it was installed. Cloning didn’t work for me because of the large drive to smaller drive issue — which left me with the regular SSD as boot and the M.2 as second drive. Since my laptop is brand new and doesn’t have much personal stuff on it yet, I just decided to get a Recovery Drive USB key from HP and reload it. On a hunch I carefully uninstalled the regular SSD, leaving the M.2 as only drive. Ran the Recovery drive and the M.2 was recognized and loaded just fine (although took forever to get all the updates installed.) Read HP forum and watch YouTube reference all the installation iterations. The 860 EVO this review is about ran smooth as silk from the beginning appears to average about 540-550 read down and about 490-505 write (seq), compared to about 520 read and 490 write on the regular SSD above. I did try out the Samsung Magician software (a caching program using M.2 and system memory to speed things up) and that showed about 4700-5000 read and 4000 write. Seemed snappier to me, but read all the pros and cons on line because everyone doesn’t agree on how good it is. Bottom line — the 860 EVO M.2 is a brand new successor to a tried and tried product (850 EVO M.2) and I think it shows. I expect to have good service and modestly better performance. At this point I would recommend any of the 850-860 line SSD or M.2 drives to a friend.
