Back up your files anytime with the Maxtor OneTouch button, or run automated backups with the included Dantz Retrospect Express software. Use the spacious 250GB drive as extra storage for your videos, photos, graphics, music and more. It's built for Macs - it's pre-formatted, has a FireWire connection and is powered by the Oxford 911 chipset. Enclosed in the anodized aluminum case is a speedy, a whisper-quiet 7200 RPM drive with 8MB cache buffer.
