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.
AS SSD uses incompressible data so the sequential write speed is lower than it would be otherwise. These scores indicate how far ahead the Vertex 3 240GB MAX IOPS is with this particular suite, thanks to the staggering performance in the 4k-64Trd read test, scoring over 250MB/s.
