Thunderbolt is the fastest, most versatile I/O technology there is. And with Mac Pro, we’re jumping even further ahead. Thunderbolt 2 delivers twice the throughput, providing up to 20Gb/s of bandwidth to each external device. So you’re more than ready for the next generation of high-performance peripherals. You can connect massive amounts of storage, add a PCI expansion chassis, and work with the latest external displays — including 4K desktop displays and peripheral devices capable of broadcast monitoring in 4K. And since each Thunderbolt 2 port allows you to daisy-chain up to six peripherals, you can go all out by plugging in up to 36 external devices via Thunderbolt alone.
