This high speed serial interface enables fast data transfer from external peripherals such as external hard disks, digital cameras and video cameras. Nearly four times the transfer rate of USB3, it features one external Thunderbolt output port, one Display Port input port and one internal header. Thunderbolt™ 2 technology is a transformational high-speed, dual protocol I/O that provides unmatched performance over current I/O technologies with 20Gbps bi-directional transfer speeds. It provides flexibility and simplicity by supporting both data (PCIe) and video (DisplayPort) on a single cable connection that can daisy-chain up to six devices.

The HP Thunderbolt™ 2 PCIe Card is backward compatible to allow your Thunderbolt™ devices to operate with no cable adapters needed.

Thunderbolt technology dramatically increases the data transfer rate enabling faster backup, editing and file sharing, significantly reducing the time to complete key tasks. Thunderbolt technology was specifically designed with inherently low latency and highly accurate time synchronization capabilities. These features enable extremely accurate audio and video creation, playback and editing that no other standard interconnect technology can match.
