Basically, I'm looking to test the loading speed of SDHC cards compared to gamma and usb 2.0 drives. Now, the wii dvd drive runs at 6x which ~8MBs. This puts gamma at 3x so ~4MBs. Class 4 SDHC has a minimum speed of 4MBs while class 6 has a minimum speed at 6MBs. This puts the minimum loading speed from the SDHC cards somewhere in between gamma and the max dvd read speed (thats what i'm thinking). (USB 2.0 is far above the dvd read speed and shouldn't matter for loading). Thus, I want to know whether loading issues are going to become a problem on SDHC cards. I want to know of a game that had the most loading problems on gamma (stuttering during movies, etc) so I could use that game to test out different cards to see whether this minimum sd speed is gonna become an issue.
