Thunderbolt™ 3 brings data transfers at speeds up to 40Gbps over USB-C, enabling a superset of standard USB-C to truly enable one compact port that does it all – delivering the fastest, most versatile connection to any dock, display, or data device. For the first time, one port can connect numerous Thunderbolt devices, any display, and billions of USB devices (additional adapters may be required). Thunderbolt 3 cables are primarily used for connecting docking stations, high performance data storage solutions, peer-to-peer networking, and more.
