James, sent you a PM. Shifter, James, and anyone else, what dictates what RAID version you should run?

Here is my criteria - not only do I not want to lose data if one drive fails, I don't want to have to then drop everything and frantically fix it for fear that a second drive will fail, I want to be tolerant of multiple drive failures. I also do not want to rely on restoring from backup because it takes a long time and I have had bad experiences with restoring from Time Machine (like, it DIDN'T WORK!) so now I use Time Machine and Carbon Copy Cloner.

I was thinking a 4 bay RAID enclosure, but to be tolerant of two drive failures I'd need to mirror all 4 drives, is that ridiculous?
