Then there are the Keep in mind that this is hardware failure protection only. If your software corrupts a file, then raid 1 will happily corrupt the copy on the other disk. Keep a backup system in place, and don't rely on raid to back things up. Raid will just help keep your server up. Nobody suggested otherwise, I just thought it would be nice to reinforce the fact that raid isn't a replacement for frequent backups.
