Being able to perform reliable I/O tests on a storage system is something that can digress into art. And it’s both the art of defining trustworthy and repeatable methods, but sadly more often the art of configuring ad-hoc tests in order to make the measurement tool say what the vendor want to be said; faking I/O tests is one of the easiest tasks, and often you only need to omit certain parameters in the published results as latency or block size in order to make them completely different.
I choose to follow a different path and I created my own solution. I have no claim this is going to be the best one. But I think is a simple way to run reliable tests, and most of all it creates easily repeatable tests, so you can then compare the results.
