My recent experiences with RAID have been unhappy ones...

I'm trying to remember what all the RAID numbers mean, I always get them mixed up. Is RAID 0 the one where it's merely striped and not mirrored? As in, that's the one that's not redundant? As in, you're doing that to get speed and space rather than to get redundancy?

If so, I recommend highly against it. By having two non-redundant disks, you're DOUBLING your chances of a failure. I've had that actually HAPPEN to me in one of my servers, so I speak from experience.

Even if RAID 0 is the one that's mirrored drives, I'd almost say forget it anyway, after seeing all the problems my friend Tod had with all of his RAIDed systems. He's lost data because of a controller failure, where plugging the drives into another controller, even of the same brand, did not recover the information.

If you do decide to go ahead with RAID, make sure you've got the data backed up somewhere nightly.
