    Do games run smoother? I was also wondering whether it really mattered if I get a class 2or 4 since Best Buy doesn't seem to stock class 4 cards that aren't PNY.

    The class of a card generally means how fast the constant read/write speed is, but it also can effect response time.

    I'd go with a Class 4 or better. Class 2 may be too slow for some games.

    Also, keep in mind that some brand's Class 2 cards may be faster than some Class 4's. Eg: My Sandisk C2 is faster than my Kingston C4.

    class x means read/write minimum afaik. Although it might be possible some cards are faster than indicated, it's rather unlikely. Class 4 seems to be the best (some class 6 have been seen to actually induce problems). That said, I've a Class 6 Transcend (brand, so not just SD [​IMG] ) 8GB ... no problems found.

    Oh yeah, brand of card still says more than an indication ... browse around for names, I think Kingston (Taiwan, or was it Japan?) and Transcend were usually the better ones I think. Haven't been looking for a while though, best is to check other flash-card brands and see with which they have trouble with ...

    still testing Class 2 pqi microSD 4GB HC. Am using Kingston 4 and 8GB.

    class 2 are no-no for me from now on even though they are fast as you said. I prefer class 4 or 6

    Well you would say that wouldnt you as you are expecting a nice fast sandisk 8gig ultra class 6 soon(Sad as i only have the 4gig version) [​IMG]

    I must say though that sandisk are a very solid relable card and my ultra class 6 runs smooth with no problems

    * Class 2: 2 MB/s - 13x
    * Class 4: 4 MB/s - 26x
    * Class 6: 6 MB/s - 40x

    Kingston's should be reliable.
