If Phil Turmel chimes in, he'll tell me off for telling you to spend money :-) If you are an impecunious student, and your data will fit on 2TB, then beg borrow or steal :-) a 2TB drive. Use that as your backup, mirrored, as I said, and then you can combine the two constellations into a 2TB raid0, and add that in as the second half of your mirror. That will at least give you a working, safe, raid system. Cheers, Wol
