Assuming that, in this case, it is data corruption that has caused the "server" to crap its dacks, then that same corrupt data would have been written to all other drives. Subsequently, you would have a pile of drives with the same corrupt data, no matter what RAID level you are running. Even if the drive had developed bad sectors, more than likely some form of garbled data would have been written to the other drives, hence again you would have pile of useless drives. I was having this exact same conversation with someone else the other day.
Edit...Actually, yes, RAID 1 would be beneficial here, as you would have more drives to play with, without totally loosing everything in the event of a stuff up :-D
