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 deals exclusively with incompressible data, and we can see the proprietary Toshiba controller performs very well in this situation. The 480GB drive comes out top in this test, by a small margin.
Some other comparisons from leading manufacturer drives, which we have tested in recent months.
