Yapt v0.3
Yapt v0.3
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.
Colossus sticks mostly with the rest of the pack on random and sequential reads, while turning up the heat on both sequential and random writes. Remember what is considered random to Yapt is actually considered more sequential by most SSD’s. The jump at 128k on random writes suggests a hard-coded 128k stripe size of the Silicon Image RAID processors.
