LaCie was among the first on the scene to support Intel (and Apple's) Thunderbolt specification with the Little Big Disk. The original Little Big Disk combined two 2.5" HDDs or SSDs into a single, externally powered Thunderbolt enclosure. The result was a relatively portable way to add a bit of high-speed storage to your portable Mac.

With the introduction of Macs equipped with Thunderbolt 2 (2013 MacBook Pro with Retina Display, 2013 Mac Pro), LaCie is updating the Little Big Disk to support the updated interface. Thunderbolt 2 doesn't change the connector or even break backwards compatibility with previous designs, but it combines channels to make better use of the 40Gbps of aggregate bandwidth that Thunderbolt always offered. Instead of offering two 10Gbps channels in each direction, Thunderbolt 2 combines them to offer up to 20Gbps in each direction. Once you take overhead into account, Intel claimed we should see a max of 1500MB/s in either direction for a Thunderbolt 2 enabled storage device.
