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.
Once again the M7V makes a fairly good fist of all the AS SSD tests. The 4K write performance is good at both shallow and deeper queue depths but once again shallow depth 4K reads are disappointing.
