Secure Digital Card or SD Card is a very popular storage media, which offers huge amounts of storage area. SD Cards are on the market for quite some time. They are constantly evolving and improving, offering higher memory capacities, faster data rates, shorter access times, etc. The SD Card standard was first introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita Electric), and Toshiba, as an improvement over existing MultiMediaCards (MMC) standard. Since then, several revisions have been made. The microSD Card is the smallest SD Card version with the only 5mm in length and 11mm in width.
