LSI tech said that my board was designed for GPU's not RAID cards, so the performance would be low.....and have a lot of problems, like all SLI MOBOs have with their RAID cards..........I think she was just fed with with all my calling, trying to get some performance out of it. lol...But any way, I seem have pretty great write performance, but read is stupid low, I am going to keep trying different combinations, trying to get decent results.
