10.4: Install Tiger on improperly set up RAID drive
Authored by: diamondsw on May 04, '05 03:15:50PM

I hope this hint is wrong - "who needs backups with a RAID-0 array"? You do - RAID-0 has no redundancy, and is much more likely to fail than a single drive (if you have four drives, for example, you have four times as many points of complete failure). Even if you meant RAID-1 (mirroring) you still need backups as a RAID-1 will faithfully copy directory corruption from drive to drive - RAID-1 only protects against hardware failure.

10.4: Install Tiger on improperly set up RAID drive

I meant mirroring. I understand RAID concepts pretty well, but forever get confused with whether RAID 0 or 1 refers to mirroring (for safety) or striping (for speed). At work, everything I control is RAID 5. Your point is well taken, however. My biggest fear is a disk failure, which I can't control. I'm pretty careful with what I install or do that could cause a corruption issue, although you could be forgiven for thinking the opposite after reading about this latest attempt at getting by on the cheap.
