I would like to know what sort of 120GB is inside the CHECH 2104A, is it one with 5400rpm or 7200rpm?
Also if it would be a HDD with 5400rpm, is it possible to switch it with a HDD with 7200rpm? Would it for example reduce loadings times even more when loading games from HDD on a with the backup manager?
Afaik: Every PS3 has a 5400 RPM. You CAN put in a 7400. But the loading time wont change at all, they even tried it with an SSD. No change in loading time. And a 7400 RPM gets a little hotter. So your system could overheat. It just isnt worth trying imho.
