I second Ben's recommendation of two parity drives.
I also recommend you configure through EVMS, rather than using the old
MD device directly. (or use a HW RAID controller)
As for the root, you can create a RAID1 (mirror) volume for the root,
and you boot off any copy of the mirror.
As Larry said, RAID5 gives good read performance (either sequential or
random) and good sequential write performance, but bad random write
performance. RAID5 also works best with large numbers of drives.
If you're looking for random write performance, consider RAID 0+1.
That requires more drives than RAID5.
