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.
I'll start by disclaiming that YAPT is not a 4K aligned test. This causes the Red (and even the VelociRaptor in some places) to see a considerable performance hit on random access tests. That said, it did track reasonably close to the AV-GP even despite having another 2 ms hit on access times.
