Before my vacation I've gained this memory card for my SLR camera (Sony A55) and have not been disappointed. But on the contrary. The camera stores the data volumes noticeably faster on the map and when reading on the PC (USB 3 provided) is a data transfer of 40MB / sec and overturned. This manages the dubbing of holiday memories in half the usual time otherwise.
The card is fully compatible with the SD-HC standard. All I tested equipment worked flawlessly with it.
