In practise this is very unlikely due to the probability of failure. Excluding external power surges and physical attack there is probably greater that a 99.9% chance that the drives will fail at a different time. I know because Linux software RAID has saved me twice. I have twice lost a harddisk in a server (same server), with the wobbles being years apart. With a disk down i only lost some productivity as the file systems went read only, until i fitted a replacement and added them in to the array. If i had only had a single disk system i would have to resorted to the tape backup! A prospect i don't fancy.
