SD Card

Secure Digital (SD) is a non-volatile memory card format developed by Matsushita, SanDisk, and Toshiba for use in portable devices. Today it is widely used in digital cameras, handheld computers, PDAs, mobile phones, GPS receivers, and video game consoles. Standard SD card capacities range from 4 MB to 4 GB, and for high capacity SDHC cards from 4 GB to 32 GB as of 2008.

The sd card measures a mere 24mm x 32mm x 2.1mm approximately the size of a postage stamp. The slim, compact design promotes easy handling, an important factor for a “bridge media” that can be moved between different products. Using decoder software, an SD compatible device can play music, video clips and more without a drive mechanism like those in CD and DVD players. This allows the equipment to be more compact and gives product designers new creative freedom. Reliability is also improved through the elimination of skipping on music and video files.
