I went a slightly different approach for my home box.  I went with 2
500G sata, use one for storage, then rsync it in the middle of the
night.  I was paranoid how easy it would be to take the disks out of
that box and throw them in something else if this system dies.  At
worst, I lose something that's not synced yet.   Of course, I could
cron the sync job to be every 5 minutes or so.

3 total drives, 1 for OS and home dir, one for storage, one for backup
of storage.
