Secure Digital Cards are a new generation memory device that offers an incredible combination of high storage capacity, fast data transfer rates, great flexibility, and excellent security.
All this in a memory card roughly the size of a postage stamp! Based on non-volatile memory components and encased in a protective molding, they do not require power to retain the information stored in them. Since they are based on solid-state components they have no moving parts to skip or break down and therefore are highly reliable.
