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.
AS SSD uses incompressible data so the results are lower than some of the other tests today. Regardless, the Revodrive 3 x2 shows huge performance gains when compared with the regular SATA 3 Sandforce powered drives. The results are particularly strong in the 4k and 4k-64Thrd tests, around twice the performance of the 240gb MAX IOPS drive.
