Remember, RAID is not a backup strategy. Fat-finger a command
like "rm -rf /" and you'll lose two RAID copies just as fast
as you'd lose one on a non-RAID disk.
RAID is for high availability. If you lose a disk, a RAID
system can keep running while you hunt down a replacement
disk. If uptime is important to you, then RAID is the way
What's much more likely for home use is the need for a backup
strategy. In that case, you'd be better off setting up the
two disks as separate partitions, and run something like
rsback to make TimeMachine-like copies from the primary to
the backup drive. This would give you the ability to restore
a deleted or changed file from one of many snapshots in the
If you lost a disk using the non-RAID primary/backup strategy,
you would lose a little time replacing the bad disk, and also
while copying files from one to the other. But that's not
catastrophic for a home system.
Again, RAID != backup. For home, I would choose "backup".
