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. 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.

With an AS SSD read score of 3334, the 4TB version of Lexar's NM790 is the fastest Gen4 consumer drive we've seen to date. However, its write score of 4560 is even more impressive.
