Introduction & Specifications
Thunderbolt, originally dubbed “Light Peak”, is a dual-protocol interface that combines PCI-Express and DisplayPort into one metaprotocol with bi-directional speeds of up to 10Gbps. The technology makes even the relatively speedy USB 3.0 interface (5Gbps) look downright pokey by comparison.
The technology supports 8 channels of HD audio, daisy-chaining, and hot-plugging and was co-developed by Intel and Apple. Although Apple got first dibs on implementing the new speedy interface on its products, plenty of other manufacturers were involved early on as well, including Western Digital.

These days, 2TB of external storage capacity in a single unit isn’t mind-blowing, but it’s certainly spacious enough for most users. Capacity is only a small part of the story here, however. WD focused on performance, with the Thunderbolt interface (including a second port for daisy-chaining) and the two 10,000RPM VelociRaptor drives spinning inside.
One of the convenient features of the VelociRaptor Duo is that it’s user-serviceable, so you can easily open up the unit and swap drives in or out--not that you’re going to want to replace those snappy 10,000RPM drives anytime soon.
There’s not much in the box, which is to be expected with an external unit such as this one; it contains a three-foot Thunderbolt cable, AC adapter, and a little installation guide.
