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.
The Toshiba controller has no real problems dealing with the incompressible data that AS SSD benchmark uses. Once again the drive excels at deeper queue depths. Also impressive is the 4K write performance.
