I currently have the choice of two MSD cards, 32GB and 64GB, to use as internal card in my N3DS (FW 9.0.0). The price difference is not an issue and in theory both cards shoudl be equally good / fast. I prefer having more memory to spare, of course. However, Nintendo recommends using MSDs no larger than 32GB. Also, every now and than someone complains about trouble with cards sized 64GB and above (this just being an example). The issues people have with 64GB (and above) card may be due to reasons other than the cards size (stuff went wrong when migrating from a smaller card, too much stuff installed, ....), but still there might be some issues specific to using cards larger than 32GB. So, any longterm 64GB card users here? Or even anyone having experience with both, 32GB and 64GB? What would you recommend to choose?
