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.
Impressive scores from the Sapphire H67 SATA 3 controller in conjunction with the Intel 510 250GB drive, scoring 483 MB/s read and 311 MB/s write in this specific test.
