LaCie’s d2 yet again surpasses expectations set by the industry’s most trusted desktop storage product. Dual Thunderbolt 2, USB 3.0, and a 4TB 7200 RPM hard disk mean any computer’s capacity for rapid project completion is greatly enhanced. Exceptionally low vibration and operating noise come as standard, thanks to an innovative, all-aluminium unibody design. This design draws heat away from the hard disk, for fan-free cooling. The integrated base provides even more space for heat dissipation by extending the enclosure’s surface area. With best-in-class pace, adaptability, and resilience, the new LaCie d2 is the new benchmark for desktop storage.

Pairing Thunderbolt 2 and USB 3.0 interfaces the innovative LaCie d2 offers the best possible speeds when connected to any PC or Mac computer, thanks to backwards compatibility. It’s possible to daisy chain up to six devices to a single Thunderbolt port on a computer because of the d2’s dual Thunderbolt ports.

This means linking up to five d2s plus a 4K display to a Mac’s Thunderbolt port, offering scalability and convenience to 4K or other workflows, isn’t just a possibility but actually operationally feasible.

The LaCie d2 couples best-in-class interfaces with a Seagate 4 TB 7200 RPM hard disk. The end result is scintillating speeds of up to 220 MB/s - professional components yield professional speeds. With this pace storing and browsing a massive RAW Adobe Lightroom library with zero lag is possible. Lightning speeds and industry-best capacity mean the LaCie d2 is the ideal solution for storing large files and archiving projects.
