OCZ Vertex 3.20 240GB Full Review - Vertex 3 Pushes 20nm Flash
Yapt (yet another performance test) is a benchmark recommended by a pair of drive manufacturers and was incredibly difficult to locate as it hasn't been updated or used in quite some time. That doesn't make it irrelevant by any means though, as the benchmark is quite useful. It creates a test file of about 100 MB in size and runs both random and sequential read and write tests with it while changing the data I/O size in the process. The results are a good look at overall drive performance.
Yapt shows most all STA 6Gb/sec units saturating the interface, save the Samsung unit, which does not play nicely with this particular test.
