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 USB 3.0 and a 7200 RPM hard disk. With an innovative aluminum unibody design, you'll notice incredibly low vibration and operating noise. Introducing the new standard for desktop storage.

Versatility for Professional Environments

Featuring the next-generation USB 3.0 interface, the LaCie d2 delivers fast speeds on any late-model PC or Mac computer. And since USB 3.0 is backward compatible with USB 2.0*, the most common interface on the planet, you can access your files from any computer.

No-Compromise Speed for Leaner Workflows

Professional components yield professional speeds. The new LaCie d2 combines a high-performance interface with a Seagate 5 TB 7200 RPM hard disk, resulting in stunning speeds of up to 200 MB/s. Excellent performance plus industry-best capacity make the LaCie d2 the perfect solution for storing large files and project archiving.

With this speed, it’s possible to store and browse a massive RAW Adobe Lightroom library with zero lag. And videographers can transport and then quickly transfer hours of RAW video footage onto a RAID backup device.

Innovative Design, Breakthrough Durability

When recreating the industrial design of the d2, LaCie focused relentlessly on reliability and usability for professionals.


  • Unibody Enclosure - Forged from a single piece of aluminum, the casing provides uncommon rigidity for long–term durability and premium quality.
  • Power–Saving Mode - Disk spins down automatically when the host operating system goes to sleep. Or, use LaCie Desktop Manager to configure the product to spin down disk after a specified amount of time.
  • Fan–Free Cooling - The broad, seamless surface area of the unibody enclosure — which includes the integrated base — dissipates heat effectively. As a result, the cooling system prolongs the lifespan of internal components while enabling ultra–quiet operation.
  • Integrated Cable Management - Prevent accidentally disconnected interface or power cables without compromising the look and design of the product.
  • Anti–Vibration Features - Extruded seams, cushioning base, and vibration–dampening hard disk mounts combine to dramatically reduce hard disk vibration.

Perfect for Professional Environments

With a bundled professional backup software suite and compatibility with Time Machine™ and Windows Backup, the LaCie d2 includes everything you need for secure backup. This product also includes LaCie Private-Public software, which lets you prevent unauthorized access by password-protecting volumes with AES 256-bit encryption.

For the ultimate in peace of mind and value, the LaCie d2 features a three-year limited warranty. It includes comprehensive, complimentary web-based resources, expert in-house technical support, and worldwide repair and/or replacement coverage. You can even upgrade this service with warranty extensions, fast product replacement, and even data recovery services.
