Hello There. Have total, 4 cards of different manufacturers, but none is as fast as the one of you. (Usage = Roland Keyboard) For comparison = when switched on and upload the data, need the 128 MB card, something to the 15-20 seconds, and this at double Datenmenge.Keine my other cards, this has, for me, the important advantage. Who needs so invite, in a very short time, and data to work, I can recommend the card very much.
