Here's an excellent
duscussion of RAID 5 vs RAID 10
by Art Kagel.
I would definitely warn against RAID 5, even hardware RAID 5, unless you're doing 95% or more reads. The performance hit is horrible, even worse for software raid, and why? To save disks? You already have 8! Build a 8-disk RAID10 (or 6 disk with two hotspares) and be done with it. You'll never use all that storage anyway. Performance will be phenomenally better for all sorts of applications that can use the storage. If you're going to go with a card like Promise, be sure Linux includes the driver in the kernel. I had a lot of trouble with a Promise card because the driver was only available on the Promise site for certain versions of Redhat, so I was stuck and couldn't upgrade (or was afraid to). That can be a real limiting factor.
