The first tenet of system administration is: if it ain't broken don't fix it.

RAID1 improves robustness. It is not a substitute for backup. Why you say?
Because hardware failure is not the only cause of losing data.

Thumb rules? Slower disks are more reliable and that is why they are 
preferred for backup. In places where access to server rooms cannot be
controlled, access to drawers can still be.

Hope that helps.
