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 ASSSD benchmark shows the DC400 to be a pretty fast drive with strong write speeds at shallow queue depths. However, at deeper queue depths this swings around in favor of a really good read performance.
