My PS3 is one of the original 60 GB models. Right now it's upgraded it to a 250 GB, 5400 RPM hard drive. I just placed an order for a 500 GB, 7200 RPM, Solid State Hybrid Drive. It's basically a 500 GB drive, with 4 GB of flash, and the smarts to copy frequency requested disk sectors into flash.
I was worried about moving up to a 7200 RPM drive, because of the warnings about extra heat. But this drive draws less power than the original 60 gig model. So its thermal load should be able to be handled without any problems (I also upgraded the heat sink compound to Arctic Silver 5 some time ago).
I'm getting this drive mostly for the extra storage, but if it improves performance of some games, that would be nice too.
