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. AS SSD includes a sub suite of benchmarks with various file pattern algorithms but this is difficult in trying to judge accurate performance figures.
Exceptionally strong read results, although the write performance lowers the overall scoring parameter with this incompressible data test.
Above, some comparison results from other leading solid state drives.
