Western Digital My Book Premium 320 GB External Hard Drive

Features:

• Easy to set up, easy to use -- Installation is a snap because you don't really "install" this drive, you just plug it in and it's ready to use. There is no CD to install; the included software loads from the drive the first time you plug it in. 
• Dual interface — For all-out, high-speed performance, FireWire 400 is the interface of choice. For convenience and compatibility among multiple computers, USB 2.0 is the way to go. How do you choose? With this drive, you don’t have to choose — you get both interfaces on the same drive. 
• WD Backup software — We've provided software that makes backing up your data as easy as possible. With a few simples steps you can back up all your data files or just save your picture and music files. You can also set scheduled backups, so you don't have to think about it again. 
• Built in Capacity gauge — See at a glance how much space is available on your drive.
• Intelligent drive management features — The My Book drive turns itself on and off with your computer and Safe Shutdown™ prevents the drive from being powered down until all your data has been written. 
• Smart design — The elegant case, iconic of a book, takes up less space on your desk, stacks horizontally, and allows two or more drives to nestle neatly together like volumes on a shelf. 
• High quality hard drive — Inside the case is an exceptionally fast-ultra quiet, cool-running hard drive from Western Digital.
