Secure Digital Extended Capacity card (SDXC)

Contributor(s): Stan Gibilisco

A Secure Digital Extended Capacity (SDXC) card is a very small flash memory card that resembles a SD (Secure Digital) card, but has far greater storage capacity. SD and SDXC cards make storage portable among devices such as smartphones, eBooks, digital cameras, camcorders, music players, and computers.

The Extended Capacity (XC) format increases maximum SD storage capacity from the previous 32 GB (gigabytes) to 2 TB (terabytes), an increase of more than 60-fold. Engineers have attained a DTR (data transfer rate) of up to 312 Mbps (millions of bits per second) with SDXC devices. The XC technology was originally conceived for the camcorder market, but it also allows for greatly increased storage in general applications as well. A 2 TB SDXC memory card can store up to about 100 full-length movies, 480 hours of music, or 136,000 high-quality color photographs.

SD and SDXC cards are provided by the SD Association.
