Do you play games off of the SSD? I notice you said you store them on the HDD.
Well, I was trying to keep it simple without getting into my own setup too much because I think the main benefit is having Windows and your applications on the SSD. But the answer to playing games off SSD is "yes and no" so here's how I actually have it set up:
120GB Corsair SSD - Windows, apps, files
640GB WD Caviar Black HDD - Steam games, all 80 of them....
60GB OCZ SSD - GoG games, StarCraft 2, a couple games I got on Impulse when it was still Impulse
(The OCZ SSD used to be my system SSD, but 60GB turned out to be too small to work well and someone game me the new one as a gift. Otherwise no reason I would have had 2 SSDs.)
So, the great majority of my games are played off the HDD and some are on the second SSD. Frankly I was surprised how little difference the SSD tends to make for games. Old games often load fast no matter what, and I really only noticed a big improvement in StarCraft 2. I didn't feel any difference at all for example in Bioshock or Far Cry 2 (though of course I didn't formally benchmark or anything).
Like I said, I think the main benefit is having Windows/apps/files on an SSD because it keeps the entire OS incredibly quick and responsive. And of course it's way too expensive to have enough SSD capacity to store a large game collection.
Not sure if that answers whatever questions you may have been getting at?
