Oh man. can you set up a guide sticky for us to bench iometer? Ive been through this with paul so many times. I think it needs to be on paper. there are so many settings I alsways get lost. just make a sticky and we can all follow it and have something to follow once and for all. I'm gonna be out setting up the raid again and reinstalling. so this is what I'll do:

LSI

raid0 128kb
read ahead'
read/write
io direct
drive cache enabled
always write back
ncq disabled
bbu off
