The Iomega REV 35GB/90GB** USB 2.0 external drive provides compatibility with both desktop and notebook computers. The small and light drive can be easily transported to different environments — so you can backup your work files and then take it home to backup your personal files. The drive is backwards compatible with USB 1.1, but a USB 2.0 connection is recommended so you can take advantage of the ridiculously high speed and superior performance of the Iomega REV drive. It also has a unique stackable chassis so multiple drives can stack nicely on your desk. The external drive is bootable on systems with BIOSes that support booting from an external USB device.
