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 only deals with incompressible data and Sandforce 2281 drives will often score quite badly in this test. The Marvell SS889175 controller in the SanDisk however scores well, slotting in just above mid way in the table above.
Some other comparisons from leading manufacturer drives, which we have tested in recent months.
