Many new :motherboards have built in IDE RAID (level 0,1) now, and they work very well. :Usually, I slap another drive in, and have tar's (compressed) run via cron. Mirroring only helps with redundancy due to hardware failure. I've seen multiple mirrors perfectly working with unusable filesystems on them due to metadata problems. RAID[0|1|0+1|3|3+1|5|5+1...n|n+1] is not in any way shape or form a replacement for backups.
