I actually have my storage broken up a little more partially for that reason.
I have a 40GB system disk (with log files and sql)
4x400GB disks in raid5 & 3x750GB disks in raid5.
Using LVM2 over the top most of the time only one array is spun up as
my only striped volume is a temp directory (for ripping, transcoding,
dumping, etc where disk access can really bottleneck).

For even more time spun down you could have your livetv group use a
separate, single disk.

Owen.
