Macs and Thunderbolt 3

The Thunderbolt 3 connection can be used on a Mac with a Thunderbolt 3 port to reach transfer rates up to 40Gb/s bi-directional.
Using the Thunderbolt 3 connection with first or second generation Thunderbolt ports requires an adapter (sold separately) and will result in lower transfer rates (20Gb/s bi-directional for Thunderbolt 2 ports, and 10Gb/s bi-directional for first generation Thunderbolt ports).

Windows and Thunderbolt 3

Your LaCie Thunderbolt 3 storage device is certified for use with Windows PCs that have a Thunderbolt 3 port. However, you may experience connectivity issues between the storage device and the Thunderbolt 3 port on a Windows PC. Therefore, before setting up your LaCie Thunderbolt 3 storage device, please visit your PC manufacturer’s website to update your Windows PC to the latest versions of:

• BIOS
• Thunderbolt 3 firmware
• Thunderbolt 3 driver

Make certain that your PC has the most recent version of Windows 10. For questions regarding your PC, please contact the PC manufacturer. You can also review the following website for additional information: https://thunderbolttechnology.net/updates.
