Best Buy offers the Toshiba Canvio 1TB Portable USB 3.0 External Hard Drive, model no. HDTC610XS3B1, for $62.99 with free shipping ($0.06/GB). That's $7 under our December mention and the lowest total price we've seen. (It's a current low by $5, although most merchants charge $75 or more.) This enclosed 2.5" hard drive features an 8MB cache and up to 5Gb/s transfer rate.

Note that Amazon charges the same, however stock is very limited.

Update: It's now available for in-store pickup only.
