Reliably Capable.
Two decades, one purpose. Since 1997, LaCie d2 storage has been so dependable, so finely calibrated for high-bandwidth tasks, that creative pros have been able to focus entirely on what they do best: creating.

Fierce Barracuda Pro Dependability
The entire LaCie d2 family features Seagate® Barracuda® Pro enterprise-class drives for incredible reliability and performance. With industry-best capacities up to 10TB, 7200RPM 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.

More Compatibility, Space, and Reliability. Less of Nothing.
The perfect complement to SSD-based laptops and all-in-one computers, the new d2 Thunderbolt™ 3 massively expands your capacity up to 10TB for professional bandwidth-intensive creative applications. With Thunderbolt 3 and USB 3.1 speeds through the USB-C port, the new LaCie d2 performs perfectly on late model laptops such as the new MacBook Pro—as well as on USB 3.0-compatible computers. It’s also the first LaCie product to feature the Seagate Barracuda Pro HDD for industry-leading performance and reliability, backed by a 5-year limited warranty.

Thunderbolt 3: Power and Versatility
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/s* 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 laptop** through a USB-C (Thunderbolt 3 or USB 3.1) port. That’s one less cable cluttering up your desktop.

PC or Mac? USB-C, USB 3.0, Thunderbolt 3, Thunderbolt 2? Whatever the OS or host port, you’re covered, whether through included cables or for purchase separately.

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.

* Actual data rates may vary depending on operating environment and other factors, such as chosen interface and disk capacity.
** Delivers up to 15W to power compatible laptops.
