Thunderbolt technology is a transformational high-speed, dual protocol, PC I/O delivering performance, simplicity and flexibility. Thunderbolt I/O technology lets you move data between your devices and your computer with 2 channels of 10Gbps flowing both ways (upstream and downstream) at the same time. And it allows you to connect as many as 6 devices, daisy chained, through a single compact port.
How does Thunderbolt technology work?
Both a PCI Express* bus and a DisplayPort* are connected to a Thunderbolt controller. Simultaneously, traffic from both buses are packetized and transmitted over the Thunderbolt cable to a controller in a downstream device. Full bandwidth is flowing in both directions at the same time allowing more bandwidth and low overhead equaling greater responsiveness. Dual protocols allows connectivity to more devices and to multi-function devices.
