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.
The TRIM (blue) line rode so close to the 02HA line (red) that it was mostly obscured by it. TRIM did not particularly help with these larger block size tests. The new firmware helps with write speeds, but not enough to beat the OCZ Vertex in sequential writes.
