Best Buy offers the Toshiba 1TB Canvio Connect Portable USB 3.0 External Hard Drive in Black, model no. HDTC710XK3A1, for $49.99 with free shipping. (Amazon has it for the same price.) That's the lowest total price we could find by $10, although we saw it for $5 less in November. It features cloud-enabled backup with 10GB of free cloud storage, password-protected encryption, an 8MB cache, and runs at 5400 rpm.
