What are Secure Digital Memory Cards?
The Secure Digital/SD Memory Card is a highly-sophisticated memory device about the size of a postage stamp. Secure Digital/SD Memory Cards stand to revolutionize information, entertainment and communications by putting advanced digital storage technology quite literally at your fingertips.
Secure Digital/SD Memory Cards are non-volatile, which means they do not require power to retain the information stored on them. They are solid-state devices, so they have no moving parts to skip or break down. They will offer an incredible combination of high storage capacity (32 MB & 64 MB in 2000, with the promise of up to 128 MB and 256 MB in the not-too-distant future), fast data transfer, great flexibility and excellent security. And of course, incredibly small size.
Secure Digital/SD will facilitate fast, simple, secure downloading of all types of digital files, like music, movies, photos, news — even cooking instructions for your microwave. Once downloaded to your PC, you can organize and store the files as you wish. Then easily transfer the files from your PC to a super-compact Secure Digital/SD Memory Card, which will be accepted by a whole variety of future SD-enabled products. Of course, you will also be able to directly record your own audio, video, still photos, and more onto Secure Digital/SD Memory Cards, as such products become available. (ref: www.sdcard.org)
