I am looking at getting a 16GB MicroSD card for my DSTwo. I was wondering if a Patriot Signature Class 4 would be a good pick. It apparently has an 8mb/sec (not sure if that is megabit or megabyte) write speed and the 2GB Patriot brand worked great back in the R4 days. Here is the link to it http://www.newegg.com/Product/Product.aspx...N82E16820220524 .
