Product Images


Anvil storage utility show 500Mb/s Read and 475Mb/S Write consistently

Crystal Disk Mark Performance is 552 Mb/s Read and 529 Mb/s Write

ATTA Benchmark Top performance is 552 Mb/s Read and 526 Mb/s Write. Which is pretty much inline with CrystaDiskMark

AS SSD Benchmark measured 495 Mb/s Read and 483 Mb/s Write

AS SSD Compression benchmark is inline with file benchmark

Anvil Storage Utility Threaded QD Mixed Random IO scores 41346 IOPS for 4K Blocks


Samsung SSD 850 EVO displayed pretty good performance throug out the set of benchmarks. I think it shines at pretty solid IOPS numbers as well as overall throughput at around 520/500Mb/s R/W. Also for the money it is really good deal especially if you get it on sale. I got one for 205 $CAD which was about the same as Crucial MX300 but with much better performance according to various sources. Will be nice to cimpare to MX300 on the same rig and with same benches, but I don’t have one currently.
