TigerDirect offers the Western Digital 1.5TB My Book Essential USB 3.0 External Hard Drive, model no. WDBACW0015HBK-NESN, for $109.99. This $30 mail-in rebate cuts it to $79.99. With $5.14 for shipping, that's $0.06/GB and the lowest total price we could find by $14, although we saw it for $5 less last summer. 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. Rebate expires February 7.
