Kingstons SD (Secure Digital) memory cards are the latest generation memory devices that offer an incredible combination of high storage capacity, fast data transfer rates, great flexibility and excellent security in a memory card about the size of a postage stamp. Based on nonvolatile memory components and encased in a protective molding, they do not require power to retain the information stored on them. Since they are based on solid-state components, they have no moving parts to skip or break down, making them highly reliable. The SD standard provides an easy method for quickly downloading and transferring secure digital files from your computer or the Internet. By using a SD Reader (such as Kingstons FCR-U2MMC/SD or FCR-U26/1) it is also possible to upload files from your SD card to your computer. As the latest introduction in the competitive Flash Memory form factor, SD is an increasingly popular format for leading manufacturers of digital devices like, MP3 players, digital cameras and PDAs. Because of its small foot print SD makes it easy for device manufacturers to integrate expansion capability into ever smaller devices.
