    Class is the write speed, not the read speed.

    However in general higher class cards will have higher read speeds (but really large cards like 8/16 gigs can slow down more).

    Class speed does not define read speed at all. In fact it does not define max write speed.

    Class speed ONLY defines MINIMUM writing speed. It says nothing about average reading/writing speed. In fact reading speed does not matter for flashcart because we are looking for random access speed. Reading speed is for sequential access speed.

    In general if writing speed increases so is reading speed. But that is not always 100% true.

    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.

    Well actually I've used some class 6 a data 8 gb cards that seem to slow down when running the intro movie to some games I play. The lag is not present or hard to detect compared to my 8gb class 4 kingston. Maybe they lied about the class but I think your better off getting a card that is known to perform well.

    So go with trumpet's advice.

    Yep, I have a class 2 Sandisk 16GB, but in my tests, it rates a class 4 for write speed. It writes at 4.1 megs per second. Possibly, it didn't get the 4 rating because its MINIMUM write speed can dip below 4.

    All I know is it runs all the games I throw at it, AP excepted of course.

    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.

    I've got an 8GB Class 6 and my save times are a good chunk faster than on the actual game carts (specifically pokemon).

    As far as I know, Non-SDHC MicroSDs are exempt from Class Rating, so there wouldn't be one listed.
    Also, when you buy MicroSD/HCs with Flashcarts or get them free, you're typically getting cheap ones. You're always better off buying one from a reputable retailer that isn't based out of China.
