SD Card Introduction:

The SD card was jointly launched by Panasonic, Toshiba and SanDisk and released in August 1999. The data transmission and physical specifications of the SD card were developed from MMC, which is about the same size as the MMC card, measuring 32mm x 24mm x. The length and width are the same as those of the MMC card, but thicker than the MMC card to accommodate larger storage units.

S maintains upward compatibility with MMC cards, which can be accessed by new SD devices, and compatibility depends on the application software, but SD cards cannot be accessed by MMC devices. (The SD card form factor is designed with the same thickness as the MMC card, so that the SD device can fit the MMC card).
