Disks are *really* cheap. Unless you are a cheap bastard or need
10TB with the speed that only jillions of 15K RPM 73GB spindles and
a 4Gbps SAN with 64GB cache RAM can give you, no one should use
RAID-5 anymore.

Especially if it's going to be SATA drives. RAID-10 (or is that
RAID 0+1?) is all you should think about.
