While I would still recommend putting the database on it's own spindle
if you run into any performance issues, modern drives are pretty fast.
Since SATA replaced PATA local disk I/O has only been an issue for the
more extreme setups. I should note that the MythTV architecture also
improved, we write to the DB in it's own thread, read from the device
in it's own thread and write to the disk in it's own thread. This
decouples operations that could cause problems in the early days.
