RAID 5 and RAID 6 are just huge pains and terribly slow for writes
with small numbers of spindles.... ;}

In my testing I found that once you hit 10 spindles in a RAID5 the
differences between it and a RAID10 started to become negligible
(around 6% slower on writes average with 10 runs of bonnie++ on
10 spindles) while the read speed (if you're doing similar amounts
of reads & writes it's a fair criterion) were in about the 10% region
faster. With 24 spindles I couldn't see any difference at all. Those
were 73GB 15K SCAs, btw, and the SAN connected via 2GB fibre.
