Get this WD Elements 1TB USB 3.0 Portable External Hard Drive for $54.99 plus free shipping from Adorama via eBay. This was the lowest price we found by $10. This portable backup and storage drive can be powered by your USB port and runs on the newer and faster USB 3.0 spec (but is backwards compatible). It's compatible with PC or Mac. There is no sales tax (except NJ and NY).
