It should be kept in mind that for any RAID mode other than 1 (I believe), if the RAID controller hardware fails, and if the same or a similar controller is no longer available, the data on the drives may be irretrievable even if it is perfectly intact.
It should also be kept in mind that besides RAID 1 not protecting against os malfunction, accidental file deletion, virus infection, etc., it also doesn't protect against both drives being simultaneously corrupted by a failure of the RAID controller hardware. That is certainly unlikely, but it can and has happened, as reported in various places on the net.
