Samsung has been a prominent brand within the performance SSD space for a while now with products that deliver really great speed albeit at a slightly premium price. The Samsung 850 EVO was a massive success and following this, the new 860 EVO SSD line-up was launched. We were lucky enough to get our hands on the 1 TB 2.5 inch Samsung 860 EVO to review.

The first thing you will notice while scanning the Samsung 860 EVO specs is that it’s not much faster than its predecessor the 850 EVO, with marginally better read and write speeds:

Samsung 860 EVO SSD Specifications
  • Form factor: Available in 2.5 inch, mSATA, M.2 forms
  • Capacity: 250 GB, 500 GB, 1 TB, 2 TB, 4 TB
  • Sequential Read Speed: Up to 550 MB/sec
  • Sequential Write Speed: Up to 520 MB/sec

However, a big area of improvement is the long-term performance of the drive with massive gains in the Terrabytes Written rating (TBW) making these new SSD’s last considerably longer. The ratings vary according to size, as you can see in the table below, but there are improvements at every level up to an incredible 700% bump to 2400 TBW for the 4TB version:

Samsung 860 Evo SSD TBW comparison tableWe slotted in the 1 TB 2.5 inch drive to do some testing, using a top end system to ensure there were no bottlenecks (i7-7700k CPU, MSI Z270 Gaming Pro Carbon motherboard along with 32 GB Corsair LPX RAM). We were impressed with the results although they are very similar to results from the 850 Evo as expected. We used AS SSD’s 1GB sequential test, which reads and writes 1GB of files in adjacent locations on the SSD. Your SSD doesn’t typically behave in this way, but it’s a best-case scenario and often the one that’s quoted by drive manufacturers. In this test, the Samsung 860 EVO managed 524 MB/s read and 476 MB/s write which is as expected.

We then took overall scores from multiple AS SSD tests to get a reading across the range of tests and compared this to a couple of drives that we had handy to give an idea of relative performance. We paired it up against an older Corsair Force 3 and the top of the range Samsung 960 PRO NVMe drive to get an idea of where the Samsung 860 EVO fits (we know it’s unfair but its worth looking at how the options compare given their different price points and didn’t have an 850 EVO on hand).

In this case, we were quite impressed with the Samsung 860 EVO as it smoked the Corsair drive and did a good job of pushing it’s bigger brother as well, with the write speeds showing very similar scores.


The new Samsung 860 EVO is a great drive with solid performance and now seriously enhanced longevity, but it’s not much faster than the older 850 model. The big advantage with the new launch is that the prices have come down for the older 850 models (Evetech have been running promotions recently) so there are some solid bargains to be had. If you are looking for a workhorse SSD that lasts and performs well then you would want to look at the new Samsung 860 EVO for sure. The 860 does look to continue Samsung’s deserved position at the top of the performance SSD pile and you can’t go wrong picking up one of these little guys.
