/Facepalm at the last few posts.
Every game uses the HDD as cache EVERY GAME. But that doesn't change the fact that if you have a SSD the read speed is gonna be 10 times faster than the fastest blu-ray drive on the market. Having cache at a seperate HDD or a different partion is just as effective as having disc plus cache. (Even more so due to the faster read speed from the HDD).
Pre rendered cut scenes is the only thing that will take advantage of bigger discs (only because you don't want 20GB of junk lying around on your HDD wasting space), rest will be better of the HDD drive in every way imaginable. Pre Rendered cut scenes is imo a thing of the past, but i guess it helps some games like FFXIII who is like 70% made up of it.
Games like Halo 3 who where slower of HDD was only because the way that game was scripted, every game made today (for the 360) loads faster from the HDD. Even if its only like 2 second difference, there is a diffrence. In most games there are a huge difference.
