SDA today has about 1,000 member companies. Secure Digital includes five card families available in three different sizes. This section does not cite any sources. The SD specification defines a card called Thin SD with a thickness of 1.

4 mm, but they occur only rarely, as the SDA went on to define even smaller form factors. The card’s electrical contacts are recessed beneath the surface of the card, protecting them from contact with a user’s fingers. The SD specification envisioned capacities and transfer rates exceeding those of MMC, and both of these functionalities have grown over time. For a comparison table, see below.

While MMC uses a single pin for data transfers, the SD card added a four-wire bus mode for higher data rates. Full-size SD cards do not fit into the slimmer MMC slots, and other issues also affect the ability to use one format in a host device designed for the other. January 2006 and defined in version 2. 0 of the SD specification, supports cards with capacities up to 32 GB. The SDHC trademark is licensed to ensure compatibility. SDHC cards are shipped preformatted with the FAT32 file system.
