RAID is designed to protect against hardware failures and provide better performance but if there is a problem with the FAT (due to a bug or a virus or something else) it will effect the entire RAID array since Drive B will be a mirror of a bad Drive A.
RAID or no RAID, regualr back ups should be done.

If it was simply a bad disk error as wizdom said then having RAID 1 setup even as a mirror would work well. Disk corrupts, computer shuts down, reboots using other HDD, then just stick another HDD, it gets mirrored and you're set again. Of course if it is from something malicious then there are more likely problems, but they are less likely to happen than failures -- depending on who and how many people you piss off.
OH, I should add the server of mine which will be up Monday ready for hosting has RAID 1 configuration.
