AS SSD is a great free tool, designed just for benching Solid State Drives. It performs an array of sequential read & write tests, as well as random read & write tests with sequential access times over a portion of the drive. It uses incompressible data samples which many drives struggle with, so results can be viewed as the worst-case scenarios.
AS SSD includes a sub suite of benchmarks with various file pattern algorithms but this is difficult in trying to judge accurate performance figures.
The AS-SSD read score of 2914 is good enough to see the Lexar Professional NM800 Pro Heatsink at third position in our results chart with the write score not too far behind at 2907.
