Raid-5 uses a parity set. If a drive goes down, its likely that you will have to spend time rebuilding the array.

As long as cost isn't too prohibitive, I would recommend RAID-10. It is RAID-0+1. More or less, you use half of your
drives as a stripped array, for speed, but the other half is a mirror, for redundancy.
