The main benefit of SSDs is much quicker random access time and this would be obvious even with SATA-I. With SATA-II, the SSD probably already loads game data faster than the CPU can process it.[/quotemsg]
I can say that on a PS3, a SSD doesn't do much good ( and I believe that's on SATA I ). Playing off the disc means the OD drive is the bottleneck. Even when playing games completely on the hard drive you don't see a whole lot of improvement. I've got a 500GB hybrid drive in my PS3 right now and I've seen it shave a few seconds off long load times ( MGS 4 and GT5 are the most obvious ), but it's still not a big deal. Arkham City, Borderlands 2, XCOM, I still see texture pops and wait a while for levels to load. Of course, I have no idea if games are enforcing long loading screens a la Mass Effect 2 on PC.
Now with the shift to newer architecture, that all may change. But first I'd want to make sure the console supports Trim and other SSD specific commands.
