AS SSD is a great free tool designed just for benchmarking 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 2TB CRAS C930 read score of 2891 sees the drive slot into a mid-table position.
