mdadm RAID 0 with 3 drives, JFS (my favorite) or XFS file system.
Some may disagree, but in such a simple setup, I don't see any reason to
add lvm on top of this RAID array, but others may prefer it.
Also note, I don't believe you can boot off of a md RAID 0 drive, so you'll
need another driver (or network boot) for your boot partition.
