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.

SandForce is able to take the crown in writes here, mainly because the data sent by Yapt is compressible. I did expect the Octane to fare better in random reads, but I suspect the lower scores are due to our Yapt series performing different operations in rapid succession, meaning the Octane might not have been done emptying that large cache out into the flash by the time it reached the random read test, forcing it to juggle both operations simultaneously. It still did well, just not as well as was expected due to the mixed workload.
