Thunderbolt is the latest technology for connecting external devices to your PC, and may become the industry standard connection for audio recording interfaces and pro video devices.
Thunderbolt is made to daisy chain up to 6 devices without any signal loss, and can also provide up to 10 watts of power to those devices. Thunderbolt can solve computer cable clutter, because it can be daisy chained with up to six other Thunderbolt devices (Similarly to Firewire) to increase the amount of audio inputs and outputs available to you.
