I am reading a lot of mixed reviews regarding the "best" micro sdhc for use in flash carts (specifically Supercard dstwo). I know there are multiple posts for this, but have a specific item question I can't seem to find elsewhere. Basically, I already know the Kingston Japan is the best, due to it's random access memory speed, and has less chance of lagging with games such as Castlevania. I can only manage to locate a 2GB, so I will buy this solely for games I find are lagging. However, I also wish to buy a 16GB memory card for the majority of my games. According to this site: http://www.tomshardw...mance,3011.html the performance of the SanDisk Mobile Ultra is excellent (although I think that they are now classified as "Class 6"). However, I can't seem to find any useful information on this card other than it is "perfect for mobile devices". Does anyone know if this card will work with a flash cart (supercard dstwo) or is it mobile phone/tablet specific? If it does work, would the performance be the same? If there are any other suggestions on 16gb micro sdhc and/or links to reputable dealers (genuine brands only) I would be happy to hear. I hear that class 4 Sandisks speeds are great, although for other brands I would probably prefer a class 6/10.
