SanDisk USB flash drives come in a variety of storage capacities, ranging from 2 to 32GB. These flash drives allow you to back up any file on your computer onto a portable device, which may come in handy if you are a frequent traveler and will be away from your desktop computer. High-capacity cards have the capability to store large files, such as full-length movies. Copying a movie file to a SanDisk flash drive enables you to have a secure backup of the movie and to watch the file on virtually any computer without the need for redownloading it.
