I have been using the 2gb Kingston Micro SD's, but I now want to purchase a 4gb card from Newegg. I have read posts on here, but there seems to be conflicting opinions. I would prefer to go with Kingston, as I trust the brand, but I can only find class 4 cards from them. Looking specifically at this one: http://www.newegg.com/Product/Product.aspx...N82E16820134638 I'm worried though that a class 4 card will have problems with games such as The World Ends With You (which I plan to play soon). Anyone have any user experience with that Kingston card and games such as POR and TWEYU? Is class 4 fast enough for such games or should i be looking into an A-Data class 6 (which some users say A-Data cards are problematic)?
