WD Black SN850 1TB SSD Review

AS SSD is a great free tool designed just for benching Solid State Drives. It performs an array of sequential read and write tests, as well as random read and write tests with sequential access times over a portion of the drive. AS SSD includes a sub suite of benchmarks with various file pattern algorithms but this is difficult in trying to judge accurate performance figures.

Although the WD Black SN850's read score of 2682 is only good enough for second spot behind Samsung's SSD980 PRO drive, its write score of 2959 is the fastest we have seen to date for a Gen 4 drive.
