Last, class speed is rated by manufacturer. SD card association does not verify this rating. So manufacturer can rate a microSD card class 6 while in reality it is class 4. Alternatively you can have a class 2 card outperform a class 6 card.While this is true, I'm pretty sure that the SD Card Association could revoke the license (meaning they wouldn't legally be able to produce cards labeled SD/SDHC) of a manufacturer who continually produces under-performing or mislabeled cards.
Not to mention that would most likely be a huge blow to the companies image/reputation.
QUOTE(Taellon @ Oct 13 2010, 09:33 PM) Use a Class 4 Kingston 4GB MicroSD card. I have noticed that the save-times are quite a bit longer than they were when I used a 2GB Sandisk one(unkown class) on my R4. I don't know if this is because of the R4-AK2i change or if my 4GB card is just a crappy build(did come from china, free with my AK2i). I don't have my 2GB Sandisk anymore to test with that either. A few times I've been tempted to just buy a new MicroSD card, but the long save times are only noticeable on Pokemon games.
