An SD card features a high data transfer rate and low battery consumption, both primary considerations for portable devices. It uses flash memory to provide nonvolatile storage, which means that a power source is not required to retain stored data. An SD card is about the size of a postage stamp and weighs approximately two grams. It is similar in size to a MultiMediaCard, but smaller than older memory card types such as the SmartMedia card and the CompactFlash (CF card). Both MMC and SD cards provide encryption capabilities for protected content to ensure secure distribution of copyrighted material, such as digital music, video, and eBooks, but SD cards are available with storage capacities as high as 128MB, with a 512MB SD card expected to be available by late 2002. (A MultiMediaCard's storage capacity is only 64MB.) SD cards are more rugged than traditional storage media. They have an operating shock rating (basically, the height you can drop them from and still have them work) of 2,000 Gs, compared to a 100-200 G rating for the mechanical drive of the typical portable computing device. This translates to a drop to the floor from 10 feet, as compared to a single foot for the mechanical disk drive. Both MMC and SD cards use metal connector contacts, instead of the traditional pins-and-plugs, so they aren't as prone to damage during handling. The SD card was jointly developed by Matsushita, SanDisk, and Toshiba.

Sometimes there's one right answer, but more often than not (just as in real life) there are several ways to approach the problem -- and that's why reading how other people would troubleshoot the Challenge is a fun way to learn.
