My Nvidia ION2  Atom 525 mythtv 11.10 setup uses 2x1TB HDDs as a RAID 1
for media (/var/lib/mythtv) and 1x60GB SSD for everything else. I can't
say I notice any difference  in performance (it just works, recording
and playback of HD TV) but it is a lot quieter and cooler than just
using HDDs.  I've run a non-ION2 mythtv 8.10 system using a 30GB SSD and
and single 500GB HDD for media for several years now without issue. 
With the cost of SSDs falling almost daily 4 or 8GB seems too small, I'd
suggest 30GB as a minimum.
