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.

Yapt is one of those tests that does not conform to ‘standard’ benchmark test patterns, and that is precisely why we include it in our suite.  It helps show scaling with larger block sizes, which is the strong suit for lower RPM / higher density drives.  Here we see the new units really pull ahead of the pack, flexing their sequential throughput muscle.
