USB-C


USB-C protocols

USB is a serial input/output technology for connecting peripheral devices to a computer. 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 USB-C ports on LaCie 2big Dock are:

  • Thunderbolt 3 (2 ports)
  • USB 3.1 Gen 2 (1 port)

Thunderbolt 3 includes support for DisplayPort up to 5K. You can connect LaCie 2big Dock to any USB-C or USB Type A port but transfer rates vary. See below for more details.

Easy to connect

Connecting your product is easy since the USB-C cable is identical on both ends. In addition, the USB-C ports on your LaCie hard drive enclosure and computer are conveniently rounded to accept the cable end in any orientation.

Thunderbolt 3 (USB-C) cable

Thunderbolt 3 can attain up to 40Gb/s as opposed to Thunderbolt 2's 20Gb/s.

Use the included Thunderbolt 3 (USB-C) cable to ensure maximum data transfer performance when used with compatible Thunderbolt 3 ports.

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.

USB 3.1 (USB-C)–to–USB Type A cable

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.
