I recently upgraded from an old R4 to an Acekard 2i, and I was thinking of getting a new memory card now that I can use SDHC. I recall someone saying, when I was asking about the AK2i, that the speed of the card doesn't matter when using it on a DS flash card (where-as, when I got my R4, I was told to - and did - get a Japanese Kingston card for best performance). I just wanted to confirm before buying that that's true. I don't care about transferring files from my computer to the flashcard, I can wait if I need to transfer something that big, I'm just concerned about any affect on gameplay or loading while using it in the AK2i. If there'll be any performance problems I'll pay the extra money to get a class 6 card.
