One more thing... 
Does anyone know if it's possible to have Steam and some of its games installed on the SSD and also install other games on the HDD?
I play L4D2 quite a lot, so would like to have that running from the SSD, but I also play a couple of other games sometimes and they're too big to fit on my 30Gb SSD as well. Could I put their data on my HDD? Or would I need to run a second copy of Steam on my HDD with my non-L4D2 games?
