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 connector, higher bandwidth and all-new power management features. Further, USB-C ports that feature the Thunderbolt icon support Thunderbolt 3 devices.

USB-C supports many protocols:

• Thunderbolt 3: transfer rates up to 40Gb/s
• USB 3.1 Gen 2: transfer rates up to 10Gb/s
• USB 3.1 Gen 1: transfer rates up to 5Gb/s
• SuperSpeed USB 3.0: transfer rates up to 5Gb/s
• Hi-Speed USB 2.0: transfer rates up to 480Mb/s
• DisplayPort: up to 8K with compatible devices and backwards compatible to VGA and DVI

The USB-C ports on LaCie 6big/LaCie 12big are:

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

You can connect LaCie 6big/LaCie 12big to any USB-C or USB Type A port but transfer rates vary. See below for more details. Thunderbolt 3 includes support for DisplayPort up to 4K.

Easy to connect

Connecting your product is easy since the USB-C cable is identical on both ends. Further, the USB-C ports on your LaCie hard drive enclosure and computer are conveniently rounded to accept the cable end no matter how it is connected.

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 ports.

USB 3.1 (USB-C Gen 2) cable

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.

Make certain to use the USB-C cable included with your device. Due to poor construction, many third-party USB-C cables can cause irreparable harm to devices such as your computer and LaCie device. LaCie is not responsible for damage to your LaCie 6big Thunderbolt 3 or LaCie 12big Thunderbolt 3 caused by third-party cables.

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 hard drive 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.
