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 1TB XLR8 CS3040 didn't seem to handle the rigours of the ASSSD benchmark very well at all, sitting in the last place in our results chart.
