With Mavericks, Apple added one more trick up its Thunderbolt sleeve: the ability to create a 10 Gbps connection between Macs using IP over Thunderbolt. With six available Thunderbolt 2 ports on the new Mac Pro, that adds up to a plethora of possible peripherals.
But that’s not all: you can also daisy-chain up to six Thunderbolt devices per Thunderbolt port on your Mac.
Not only is it capable of 10 Gbps of bi-directional throughput on each of the dual channels in its original form and 20 Gbps max on a combined channel in Thunderbolt 2, it can also transport PCIe, USB 3.0, FireWire, Mini DisplayPort and gigabit ethernet data. I think all Mac users can agree: Thunderbolt is both fast and flexible.
