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.
These results have knocked the OCZ Vertex 4 off the top slot, and nothing else has matched the performance of the 256GB Vector since we reviewed it. The 512GB Vector scores a little higher, taking top spot in the graph behind the Hybrid RevoDrive and RAID 0 Intel 520 drives.
Some other comparisons from leading manufacturer drives, which we have tested in recent months.
