I have been using SQLIO as a tool to estimate storage performance capacity for a few years. Its a great tool - really flexible and powerful. The biggest cost for me has been analyzing results. For my tests I don't do anything fancy. But I do need to analyze results easily & quickly, to compare one storage subsystem/RAID Array/SAN against another.
So, I put together this Windows program. Just open your SQLIO result .txt file for quick analysis. If anyone wants to use it, its freeware.
