Just realised sandisk had this Pro duo memory stick and the new Ultra Memory stick.
Read speed is 6mb/s and 10mb/s respectively and write speed is 5mb/s and 9mb/s respectively.
Any idea if the speed will make a huge difference ingame? Apprantly some games are very laggy, like GTA, WWF, etc. Or does the speed increase only affects the loading of songs, scrolling of games and videos at the menu screen?
