I found a good deal of Sandisk 4GB SDHC that I plan to purchase for my DSTT. As far as I know, people have been complaining Sandisk's performance in a few games compared to Kingston's in the non-SDHC era, then again I heard SDHC cards read much faster then non-SDHC so there shouldn't be a problem at all, but I am curious and wondering if I should save up a few bucks more for Kingston's. I searched the forum, some people have confirmed 8GB Sandisk(Class 4) working great, but what about 4GB(Class 2)? How does it perform? Do their "Class" affect anything at all? Thanks in advance.
