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 read score of 468 for the DC500R is enough to put the drive into fifth place in our results chart, but more impressive especially for a read-centric drive is the write score of 527, the second-fastest score we have seen for this group of SATA SSDs.
