More Compatibility, Space, and Reliability The new d2 Thunderbolt 3 massively expands capacity up to 10TB for professional bandwidth-intensive creative applications. Featuring 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 computers. It's also the first LaCie product to feature the Seagate Barracuda Pro HDD for industry-leading performance and reliability. Fierce Barracuda Pro Dependability The LaCie d2 Thunderbolt 3 features 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 the fastest and highest capacity desktop drive available. The d2 story Forged from a single sheet of aluminium, the enclosure provides uncommon rigidity for long-term durability. The whisper-quiet fan and heat-dissipating aluminium enclosure pull heat away from the HDD, keeping it running fast and healthy. Up to 240MB/s means less time moving files from camera cards into Adobe Lightroom—and more time filling camera cards with new photos and footage. Dual Thunderbolt 3 ports means 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. Power a compatible laptop (up to 15W) through a USB-C (Thunderbolt 3 or USB 3.1) port. That's one less cable cluttering up your desktop.
