[MrGuvernment]

Hello my experts, i wished to ask you before i take on a small task.

i now have an ICH9R based mobo and various harddrives, to which i am going to get the best out of which i can, testing varies raid set up, using matrix raid..


software i know of for testing

HDTach
HDTune
IOMeter.


how many runs of each should i do to determine a suitable average? 3? more?

i plan to make a thread of my results, almost a poor mans raid thread, so all help is appreciated
