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.
Of the three Kingston SATA based data centre drives we've tested to date, the DC450R just has the edge when it comes to the read score in AS-SSD but has the slowest write score of the three drives.
