You have good nerves. I have had enough trouble with hard disks already.
I wouldn't bet the data on 7 disks on one disk failure. BTW, a Raid-5
would not make a big difference as a disk failure frequently takes the
whole IDE channel down. And when two drives are gone Raid-5 is dead as
well.
Maybe you could install two Raid-5 devices with just one drive at one
channel. E.g. all masters form a Raid-5 and all slaves form the other
one. So when one channel goes down two Raid-5 would be running
unsyncronized, but the data was fine. Of course for this you would have
to sacrifice another disk for parity, so you would have "just"
(3 * 80 GB) + (2 * 80 GB) = 400 GB left.
On the two Raid-5 devices you could run LVM to hide the physical
seperation.
