Thunderbolt 3: Power and Versatility

Thunderbolt 3

From a single, mighty port, you get astonishing bandwidth with the versatility of the USB-C industry standard. For the LaCie d2 Thunderbolt 3, the result is performance up to 240MB/s4 for cutting-edge creative workflows, the widest compatibility, and time-saving device configurations.


Faster transfers mean less time moving files from camera cards into Adobe® Lightroom—and more time filling camera cards with new photos and footage.

Laptop Charging

It's even possible to power a compatible laptop5 through a USB-C (Thunderbolt 3 or USB 3.1) port. That’s one less cable cluttering up your desktop.

Daisy Chaining

Thanks to dual Thunderbolt 3 ports, you can daisy chain dual 4K displays, a single 5K display, or up to six total LaCie d2 drives—all through a single cable connected to your computer.


Fierce BarraCuda Pro Dependability

The d2 Thunderbolt 3 and the new d2 Professional feature Seagate® BarraCuda® Pro enterprise-class drives for incredible reliability and performance. With industry-best capacities up to 16TB, 7200-RPM performance, and support for 24/7 operations, the BarraCuda Pro is ultra-high performance and the highest capacity desktop drive available. And for complete peace of mind, it’s also backed by a best-in-class 5-year limited warranty that includes Rescue Data Recovery Services.3 What does that mean? It means that in the case of drive failure, we’ll replace your drive and recover your files with one in-lab data recovery service at no additional cost.

At CES 2017, I talked with Lance at LaCie about their new line of USB-C Thunderbolt 3 products. The D2 line of hard drives got an upgrade to the new protocol, with hard drive support up to 10 TB, but can be daisy-chained to other D2's (not in RAID).


With the new d2, LaCie again raised the bar on the industry’s most trusted desktop storage product. Get the job done faster – on any computer – with dual Thunderbolt 2, USB 3.0, and a 7200 RPM hard disk. Thanks to its innovative, all-aluminum unibody design, you’ll notice incredibly low vibration and operating noise. It’s even possible to push speeds to up to five times faster by installing the LaCie d2 SSD Upgrade (sold separately).
