Daisy Chain and Power Delivery
Use the two Thunderbolt 3 ports on the LaCie 6big/LaCie 12big for:
Direct connection to a computer that is compatible with Thunderbolt 3 technology.
Daisy chaining with devices and displays that are compatible with Thunderbolt 3 technology.
Charging the batteries of compatible devices.
Daisy chain Thunderbolt 3 devices
Thunderbolt 3 is an update of Thunderbolt 2 technology. While Thunderbolt 2 technology continues to
provide impressive transfer rates up to 20Gb/s bi-directional, Thunderbolt 3 offers improved performance
with a potential up to 40Gb/s bi-directional. Thunderbolt 3 technology also gives you greater flexibility when
using video and data, assigning greater throughput to the stream that carries the heavier load. You must have
a computer that supports Thunderbolt 3 to take advantage of the updates in performance and the intelligent
sharing of bandwidth.
Similar to Thunderbolt 2 technology, a single Thunderbolt 3 daisy chain can have up to seven devices,
including the computer. For example, you can daisy chain five LaCie 6big/LaCie 12big Thunderbolt 3
enclosures on the same line with a display.
How to daisy chain
Connect the cable to one of the interface ports on the back of LaCie 6big/LaCie 12big and to your
computer. The additional port on LaCie 6big/LaCie 12big can be used to daisy chain compatible Thunderbolt
3 peripherals, such as hard drives and monitors. If you have another Thunderbolt 3 storage device, make
certain to connect it to the daisy chain before adding compatible displays or USB 3.1 (USB-C) devices. See
below for an example of the order of devices in a Thunderbolt 3 daisy chain.
1. Computer with a Thunderbolt 3 port
2. LaCie 12big Thunderbolt 3 (Thunderbolt 3 ports)
3. LaCie 6big Thunderbolt 3 (Thunderbolt 3 ports)
4. LaCie Bolt 3 (Thunderbolt 3 ports)
5. LaCie Porsche Desktop (USB 3.1 (USB-C) port)
USB 3.1 (USB-C) devices can terminate a Thunderbolt 3 daisy chain and should always be the last device.
Note on the USB 3.1 (USB-C) port: USB 3.1 does not support daisy chaining devices. Therefore,
a USB 3.1 (USB-C) port on your computer cannot be used to daisy chain devices.
