Secure Digital
Secure Digital (SD) is a flash memory card format developed by Matsushita, SanDisk® and Toshiba in 2000, for use in portable devices such as digital cameras, handheld computers, PDAs and GPS units. Today, SD card capacities range from 8 MB to 16 GB. Several companies have announced SD cards with 32 GB. Cards with 4-32 GB are considered high-capacity and conform to the newer SDHC specification. Physically, SD cards are based on the earlier Multi Media Card (MMC) standard, but are designed in such a manner that they cannot be inserted upside down, and tend to be somewhat thicker than the MMC standard.
The mini SD card was announced in 2003 by SanDisk as a physically smaller format for the SD Specification. An even smaller form factor, the Micro SD Card followed, primarily in response to demand from the wireless telephone industry. FlashRite offers extensive support and capacity for all Secure Digital formats, including product selection, sourcing, duplication, labeling and packaging.
