The video store will take the most beating so it's not a good idea if 
you can avoid it

I'd do what I suggest in this thread
http://www.gossamer-threads.com/lists/mythtv/users/265064#265064
put /etc and a few of the more static mount points on a CF card
with the rest on a Fujitsu 200GB 4200RPM laptop harddrive.

"For the most part the data rates required by MythTV are not that high,
particularly if you've only got one/two sources and/or one/two
frontends, you could probably make do with a couple of 4200RPM jobs,
according to THG the fujitsu 200GB only consumes 2.2m max and 0.6w at idle

if you put /etc and a few of the more static mount points on a CF card
with the rest on a Fujitsu 200 you could then use LVM to join whatever's
left of that drive with another, probably resulting in around 390GB of
storage for recordings, that consume less than 5w"
