Staples offers the Western Digital Elements 3TB USB 2.0 External Hard Drive, model no. WDBAAU0030HBK-NESN, for $119.99 with free shipping. (It's the first option on the page.) (Of note, Amazon charges the same price.) That's $0.04/GB, tied with our mention from two weeks ago, and the lowest total price we could find by $5. Sales tax is added where applicable. This drive uses GreenPower technology to reduce power consumption by up to 30%.
