SanDisk’s new hard-drive backup system is a USB thumb drive that plugs into a computer like any other. Unlike other backup systems, however, it doesn’t require the installation of new software. The first time you insert the drive into your computer, a window pops up asking you to select a set of folders or a type of file–say, all MP3s. After that, pressing a button on the top of the drive backs up the selected items. The drive uses hardware-based encryption, and accessing data stored on it requires a password. Its capacity ranges from 8 to 64 gigabytes.
