What do you do when uptime is important? Do today's drives never fail? With a RAID mirroring system, you generally will have the system stay up on single drive failure, and the bad drive can perhaps be swapped hot (although I would still wait until 2 a.m. to do it so that the rebuild process wouldn't affect system performance). RAID is not a backup process/system. Back up separately, in addition to RAID. Yes, RAID controllers fail, just as any circuitry can fail, from the motherboard to the circuit board that is part of the hard drive itself. 100% uptime isn't possible without a whole lot more redundancy than just RAID.
Do today's RAID systems have S.M.A.R.T monitoring such that preliminary warning is (sometimes) provided in time to do something about it?
