Buy.com offers the Western Digital 2TB My Book Essential USB 3.0 External Hard Drive, model no. WDBACW0020HBK-NESN, for $99.99 with free shipping. (Amazon has it for the same price.) That's $0.05/GB and $10 under last month's mention, although we saw it for $10 less in November. (It's a current price low by $19.) This drive is purported to run 3x faster than a similar USB 2.0 device when connected to a USB 3.0 port. It also features password protection with hardware encryption.
