Does anyone know if there are any functional differences bewteen brands of SD Cards?..for example Panasonic, SanDisk, High Speed Lexar...I understand Matsushita (Panasonic), SanDisk and Toshiba jointly developed the Secure Digital Card...Logically it would seem the SD Card being a storage media ,there would be no differences between brands, however, in electronics not everything is logical.
