Western Digital VelociRaptor 1TB Review - 10K RPM Hits a Larger Capacity
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.
Random Write access with YAPT appears to not be 4K aligned, so we see the new VelociRaptor stumble a bit there in the smaller sizes, but as sizes grow the alignment becomes less relevant and it quickly overtakes (yes, even overtaking the SSD).
