said by Subaru:yep I thought about SSD but I saw a test did on it I think it was late last year and it's not really worth it at all.. I think the only fastest speeds that you could tell was deleting games.
Hmmm I've been thinking maybe 500 GB That should hold me over for a good long while.
SSD would show its best on ps3 if you were playing a lot of games from the internal hard drive, or if it's a game that uses the hard drive of the ps3 a lot... GT5 in particular.
But how much the internal hard drive on a ps3 is used is dependent entirely on the maker of the game. Some do some very careful streaming of data from the disc at a constant rate, so the hard drive hardly gets used in those cases, and you wouldn't see much of any improvement there.
Install/delete times notably get shortened too. But again, it doesn't make sense to spend the money on a SATA III SSD because the ps3's internal interface is (IIRC) still SATA I. So a max of 150~MB/s anyway.
The bigger benefit with regard to a ps3 is the power savings, if you were that worried about how much energy it uses... or how hot the system runs.
