Hmmm... I thought I had read about folks having difficulties with the
same physical disk having to handle both the video data files and the
MySQL db access.  I had read that things got much better once they put
in a 2nd disk and moved the MySQL db there.  So I figured I'd just cut
to the chase.

I had originally thought about RAID-ing a pair of disks (which is one
of the things that led me to the 2480 chassis -- it can hold 4 drives
-- a DVD, and OS disk, and a 2 disk RAID), but then I started
wondering how much value it would had to RAID the video files.

I had thoughts of turning the MythTV box into a home backup server, on
which I could dump backups from our home (XP) PC (and possibly set it
up as a Time Machine backup server for my Macbook, if that's
possible).  In that situation, the RAID makes sense.  I forget now why
I decided that wouldn't be worth the effort, possibly because an
off-site backup of our important data files would make more sense than
something that could be destroyed by the same fire/meteor
strike/flood/whatever/ that might destroy the home pc.
