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.
The read score of 3137 in the AS-SSD benchmark is good enough to put the drive on top of the 1TB class Gen 4 drive results chart. But even more impressive was its write score of 4498.
