I'd recommend having a 'cold spare' (not plugged in disk) lying around to minimize the time you're running on k-1 disks. If downtime is not an issue, I'd not recommend having a hot spare - the mechanics on a hot spares get older (spindle motor and bearings) too, so chances are you lose the spare soon after it goes live... You realize that most cases of data loss are not disk failures, but user errors? RAID doesn't help you there, but (off-line) backup does. So, be sure to back up your data - you'll probably need the backup more frequently than you'll need to replace disks. For low-budget, I think it's much more important to have a good back up strategy than to have RAID - with daily backup, you lose at most 24h data, but with a RAID and no backup, you still lose everything if somebody hits the wrong button. cheers -- vbi -- featured product: GNU Privacy Guard - http://gnupg.org
