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 SX950 produced excellent read/write scores in the more stringent AS-SSD benchmark, with a write score of 500 being the fastest score we have seen to date for a 2.5in consumer SSD in the 240GB/256GB segment. The read score of 464 is very impressive as well.
