Dumb question, but can you still run "hdparm -t /dev/whatever" on a
SATA drive?  No matter how it's configured, it would at least give you
a ballpark figure on if the drive is configured right.  My system just
scored 11MB/sec while recording two shows and transcoding, and 40MB/sec
when it was merely transcoding.
