I dealt with a similar issue by adding an extra drive. My OS, static
media, and  MySQL are on one physical drive. I then have two more
physical disks, in my only storage group, for recordings. Myth handles
the I/O between the drives and balances reads and writes. One of the
drives also happens to be physically attached to a different computer
and shared by NFS.

Cheers,
