I updated my slim with a new 500gb hard drive. I was wondering would the hard drive cause my ps3 to lag online. When i play madden it lags sometimes.
The lag you are referring to is caused by the quality of the internet connection between your PS3 & the madden servers. Lag can also be brought into the game by other players. It should be fairly easy to tell who is lagging
changing your hdd WILL NOT cause you to lag
