 I think you would get more use out of 2 x 1 TB disks (or 1.5 or 2TB), 
mirrored (md) and partitioned and possibly using LVM for flexibility in 
migration and/or adding more disks and expanding filesystems 
non-disruptively.  Your OS wont be thrashing swap or doing a lot of IO to 
your OS filesystems (except some small amount of IO to /var to the mythtv 
databases and I've never found this to be ain issue, even with 4 tuners- 
though they were all digital nor analog YMMV for analog), so IMHO you 
would be wasting the IO capability of your OS disk.  There was a good post 
in the last week or so about about moving your Mysql tables for Mythtv 
from /var to /home to keep your OS data isolated from your user data.
