Since 2014, the Samsung 850 Evo has reigned supreme thanks to its blistering speeds, tested endurance and impeccable value. The five-year guarantee has also helped it secure its place as one of the most popular choices for most PC builds. However after three years, Samsung decided it was time for an update and they have replaced it with the brand new 860 Evo.

Features and Price:

Just like the recently released 860 Pro series, the 860 Evo is also powered by 64-layer V-NAND technology. The drives utilize an MJX SATA controller paired with 2GB of LPDDR4 DRAM (specific to 2TB models only) for enhanced speed and power efficiency.

Samsung’s claimed sequential read speed is just 10MB/s faster at 550MB/s while its sequential write speed is an identical 520MB/s. Although going by the speed it doesn’t seem like an actual upgrade, it’s the endurance department where the 860 Evo really shines. It has taken the 850 Evo’s 75-300 terabytes written (TBW) rating up to a massive 150-2400 TBW. Admittedly, that 2400 TBW figure is only reserved for the top 4TB capacity (those settling for the entry-level 250GB and 500GB models will be limited to 150 TBW and 300 TBW respectively, while 1TB and 2TB buyers get 600 TBW and 1200 TBW), but that’s still a heck of an improvement compared to what the 850 Evo first offered when it came out at the back-end of 2014 (that is, 75TB for the 120GB and 250GB capacities, 150TB for 500GB and 1TB owners,and 300TB for the 2TB and 4TB models).

As ever, the Samsung 860 Evo series is designed to be both affordable and deliver a serious amount of solid-state storage. Prices for both the M.2 SATA and 2.5-inch versions start at $94 (₹6100) for 250GB, ramping up to $169 (₹10,900) for 500GB, $329 (₹21,000) for 1TB, $649 (₹42,000) for 2TB and $1,399 (₹90,000) for 4TB.



In our testing, we saw small but noticeable improvements in the 860 Evo’s performance over its predecessor. Namely, there are 5-20 MB/s improvements in both sequential read and write speeds. The 2.5-inch version of the Samsung 860 Evo also achieved significantly higher random read and write speeds that are 60-70 MB/s faster.

One strange thing we noticed was the fact that the M.2 SATA version of the Samsung 860 Evo couldn’t achieve its maximum rated speeds in CrystalDisk Mark. The likeliest cause of these strange results are driver issues or incompatibilities with our benchmarking software, which we hope will be fixed in the near future.

Samsung 860 Evo (2TB SATA)

CrystalDisk Mark (Sequential) Read: 517 MB/s; Write: 492 MB/s
CrystalDisk Mark (Random) Read:399 MB/s; Write: 352 MB/s
10GB File Transfer: 14.58 seconds
10GB Folder Transfer: 26.91 seconds

Samsung 860 Evo (2TB M.2 SATA)

CrystalDisk Mark (Sequential) Read: 557.1 MB/s; Write: 515.9 MB/s
CrystalDisk Mark (Random) Read:243.7 MB/s; Write: 236.3 MB/s
10GB File Transfer: 13.71 seconds
10GB Folder Transfer: 25.63 seconds


The Samsung 860 Evo is an undeniably better series of solid-state drives than their predecessors. Although the speed upgrade may not seem much, they offer over four times the endurance. While we struggled to see the 860 Pro as a noteworthy upgrade, Samsung has brought its budget SSD line to flagship spec – or at least the highest spec the aging SATA 3 standard will allow.
