Secure Digital (also known as SD) is a flash memory memory card format. SD cards are based on the older Multi Media Card (MMC) format, but add little-used DRM encryption features, allow for faster file transfers over the initial MMC speed, have small switch one the side that can stop the card from being overwritten, as well as being physically slightly thicker). Standard SD cards measure 32 mm by 24 mm by 2.1 mm. There are two main types available, ones that run at regular speeds, and high-speed cards that have higher transfer rates. High-speed cards are needed by some digital cameras to record higher quality video smoothly.
