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 ADATA S599 drive puts in a good showing compared to other SSD drives used for comparison today, slightly outperforming the excellent Vertex 2 100GB unit. The Corsair F100 100GB struggles a little with the uncompressed data when performing the sequential write speed tests.
