I run RAID1 across two drives. It's actually on top of the partitioning - I have both drives partitioned the same, and each pair of corresponding partitions is RAIDed. One pair is RAID0; I use that for large temporary files from video editing.
Although people say "it's not for backup", that's really a big part of what I use it for. I'm more worried about losing data to drive failure than my own mistakes, and having it mirrored across the two drives means I lose almost nothing (instead of "back to the last backup") when a drive fails. So far I've lost one, and was up and running again just a few hours later with no real data loss. I couldn't really make backups at that frequency.
