Dell Small Business & Home Office offers the Dell 1TB 2.5" Portable USB 3.0 External Hard Drive, model no. XNWYD, for $79.99 with free shipping. That's $0.08/GB and among the lowest total prices we've seen for a 1TB USB 3.0 hard drive (although we saw a Dell 1TB USB 3.0 HDD in August for $3 less). Sales tax is added where applicable. It runs at 5400 rpm.
