BuyDig via eBay offers the Toshiba 2TB Canvio Connect Portable USB 3.0 External Hard Drive in White, model no. HDTC720XW3C1, for $69.99 with free shipping. That's the lowest total price we could find by $10, although we saw it in Black for $5 less last month. This USB-powered drive features an 8MB cache and up to 5Gb/s data transfer rate.
Update: Specs corrected.
