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.
Although the read score of 2346 in the AS SSD benchmark sees the SN580 near the bottom of the results chart, its write result of 2735 is pretty strong. Both scores are an improvement over the previous generation SN570 which scored 1539 and 2330 for reads and writes respectively.
