There's little point striping the disks cos squid will stripe for you anyway.
Besides, if you lose one disk you lose the entire cache. Squid can keep going if
it loses a "cache_dir". If ths suarts you thinking about RAID-5, don't. Squid
provides the worst-case load for RAID-5 making it far worse than individual
disks.
