Those are almost always software RAIDs, so your CPU would be doing all of the parity processing on RAID5 so performance there would quite suck. There appears very low overhead striping in a RAID0 with onboard fakeraid though, in my experience; very very fast performance there. I recall one Promise Fasttrak controller said in their documentation that when you created a RAID1 set, it would read the data in a striping pattern, essentially doubling read performance. and that was basically a fakeraid also.

_____ From: James Kerr [mailto:[email protected]] Sent: Friday, September 11, 2009 11:50 AM To: NT System Admin Issues Subject: SATA RAID Performance On my personal PC at home my mobo has a RAID feature and I have to large hard drives in there. Anyone know if I would see a performance increase if I set these drives up as RAID1 or would it just give me mirroring and no increase? What about if I added a third drive and made it RAID5?
