Personally I find it too complex and fiddly (I usually only want to test block based io and come up with separate read and write numbers), so of course I wrote my own - initially in c then decided to try out python: https://github.com/markir9/rwtest so I tend to use that now... much easier and no need to recompile for different chipsets!
