More Compatibility, Space, and Reliability. Less of Nothing

The perfect complement to SSD-based laptops and all-in-one computers, the 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 that includes Rescue Data Recovery Services.

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.

    Performance - 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.

    Compatible with Thunderbolt and Thunderbolt 2 (Mac only) - Macs with Thunderbolt and Thunderbolt 2 ports can experience high-end transfer rates with LaCie Thunderbolt 3 professional solutions. Apple’s Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter (sold separately) provides easy connection between LaCie Thunderbolt 3 solutions and Macs with earlier generations of Thunderbolt technology.

    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 10TB, 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.

USB-C: Future Compatibility

USB-C 3.1 clearly makes the most sense going forward, which is why we built the highest level of performance and compatibility into the latest LaCie d2. Take advantage of the fully reversible USB-C cables and the USB-C to USB type A adapter which can be used on any PC or Mac. You can expect up to 240MB/s for all your epic workflows along with fast file transfer rates of up to 5Gb/s.

Solid Components. Solid Investment.

    Enclosure - Forged from a single sheet of aluminum, the enclosure provides uncommon rigidity for long-term durability.

    Cooling - The whisper-quiet fan and heat-dissipating aluminum enclosure pull heat away from the HDD, keeping it running fast and healthy.

    5-Year Limited Warranty - Choose with confidence. The LaCie d2 Thunderbolt 3 is backed by the industry’s most generous warranty.
