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.
Once again a clear line between 3Gbit and 6Gbit interfaces, with the 910's SAS link sitting mostly just in-between the two. DC series SSDs appear extremely sensitive to non-4k-aligned IO, and YAPT is not a 4k-aligned test.
