Before you do this, you may want to some serious investigation about
failure modes.
The article at http://blogs.zdnet.com/storage/?p=162 was just the
first example I looked at after searching for [raid 5 terabyte].
Essentially, with today's larger disks, the time it takes to do a
rebuild is sufficiently long enough that the risk of a second drive
failure during the rebuild is high enough to be troublesome.
