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.

In the AS-SSD benchmark, the WD Black SN850X did seem to lag behind a good selection of its competitors as its read score of 2778 is only good enough to put the drive into a mid-table position in our results chart unlike the write score of 3042, which is much stronger.
