RAID protects you from a drive failure. If an entire RAID group fails (for whatever reason), you'll need to recover any non-fallback
tables on your system.
Some reasons for an entire RAID group failure include:
Cabinet level failure of your disk array cabinet Loss of all nodes in a clique before any pending updates could be saved
I suppose there are other (more obscure) reasons. I don't have a good feeling for how frequent either of above phenomena would occur (I
suspect quite in-frequent).
