This Refurbished LaCie 1TB Little Big Disk Thunderbolt External Drive is $159.99 plus free shipping at MacMall. This drive usually costs over $300 and this is about $10 less than some refurbished models we found. This drive uses the Thunderbolt interface, which offers twice the transfer speed of USB 3.0 at 10Gb/s. Thunderbolt is found on newer models of Apple computers and some PCs. We recommend you check to see if your computer supports Thunderbolt before purchasing. A refurbished 2TB version is also being offered for $219.99. Sales tax is charged in most states.
