Without arguing, there's one thing that should be pointed out as well. While we'd never expect 2 drives to die/fail simultaneously, it can happen with the result of a surge or lightning strike. Best ways for those who's info is critical-back them up to CD, DVD or tape and take them off site as well as if ultra critical, back them up to an on line, out of area server. Nothing against mirroring though. It's an excellent idea. 3 cents and counting.
