Apparently there’s a need for “premium” micoSD cards (and the like), otherwise SanDisk wouldn’t bother producing them. The company has just revealed premium models of microSD, microSDHC and Memory Stick Micro (M2) flash cards, all featuring faster transfer speeds than conventional, non-premium cards. If you’re asking yourself, “That’s all that makes these cards premium, faster transfer speeds?” Well the answer is yes, that’s all it means.

The cards, which come in 2, 4 and 8GB capacities, should be in stores by early June.
