USB-C is the latest implementation of this standard and it provides convenient connection, higher bandwidth, and all-new power management features. USB-C ports that have the Thunderbolt icon support Thunderbolt 3 devices.
USB-C supports many protocols:
|Thunderbolt 3||Transfer rates can reach up to 40Gb/s|
|SuperSpeed USB 3.1 Gen 2||Transfer rates can reach up to 10Gb/s|
|SuperSpeed USB 3.1 Gen 1||Transfer rates can reach up to 5Gb/s|
|SuperSpeed USB 3.0||Transfer rates can reach up to 5Gb/s|
|Hi-Speed USB 2.0||Transfer rates can reach up to 480 Mb/s|
|DisplayPort||Up to 8K with compatible devices and backwards compatible to VGA and DVI|

The Thunderbolt 3 cable can also be used to connect the USB 3.1 (USB-C Gen 2) port on the LaCie 2big Dock to a USB 3.1 (USB-C Gen 2) port on your computer. USB 3.1 Gen 2 can attain up to 10Gb/s as opposed to USB 3.0 at 5Gb/s and USB 2.0 at 480Mb/s.
Use the USB 3.1 (USB-C)–to–USB Type A cable for compatibility with computers that do not have a USB-C port. The USB-C end is connected to the LaCie device and the Type A end is connected to the computer’s USB 3.0 or USB 2.0 Type A port.
Hard drive performance is limited to USB 3.0 transfer rates when connected to a USB 3.0 port and USB 2.0 transfer rates when connected to a USB 2.0 port.
