LaCie 4TB d2 Thunderbolt 2 External Hard Drive - LAC9000493U

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 dual Thunderbolt 2, USB 3.0, and a 6TB 7200 RPM hard disk. Thanks to its innovative, all-aluminum unibody design, you'll notice incredibly low vibration and operating noise. It's even possible to push speeds to up to five times faster by installing the LaCie d2 SSD Upgrade. With best-in-class speed, versatility, and durability, the new LaCie d2 sets a new standard for desktop storage.


  • Versatility for Professional Environments
    The new LaCie d2 combines Thunderbolt 2 and USB 3.0 interfaces to deliver the best possible speeds when connected to any late-model PC or Mac® computer. Dual Thunderbolt 2 ports let you daisy chain up to six devices to a single Thunderbolt port on a computer. This means that you could connect up to five LaCie d2 plus a 4K display to an iMac® computer's Thunderbolt 2 port, bringing remarkable scalability and convenience to 4K or other workflows. And since USB 3.0 and Thunderbolt 2 are backward compatible***, you always get the absolute fastest speeds your computer allows
  • No-Compromise Speed for Leaner Workflows
    Professional components yield professional speeds. The new LaCie d2 combines best-in-class interfaces with a Seagate 6TB 7200 RPM hard disk, resulting in stunning speeds of up to 220 MB/s. With this speed, it's possible to store and browse a massive RAW Adobe® Lightroom® library with zero lag. High speeds plus industry-best capacity makes the LaCie d2 the perfect solution for storing large files and archiving projects
  • Innovative Design, Breakthrough Durability
    When recreating the industrial design of the d2, LaCie focused relentlessly on reliability and usability for professionals
  • Upgradable to External Hybrid Storage
    Install the optional LaCie d2 SSD Upgrade (sold separately) to multiply speeds by a factor of five, with zero compromise in capacity. At up to 1150 MB/s, the LaCie d2 with the d2 SSD Upgrade delivers speeds that exceed the performance of even the internal SSD on your late-model PC or Mac computer – in a single-disk enclosure. Simply remove the rear panel on the LaCie d2 to install the upgrade,and instantly you have an additional 128GB of SSD storage. Two separate drives mount on the computer: one for the SSD, and one for the hard disk. Use the SSD for bandwidth-intensive tasks such as fast file transfers, audio mixing, video editing, or OS booting, and use the hard disk for file archiving. No other solution offers this level of performance and capacity in such a compact footprint
  • Packed with Value for Pros
    The LaCie d2 includes everything professionals need for secure backup: a backup software suite, and compatibility with Time Machine and Windows Backup. It also includes LaCie Private-Public software, which lets you password-protect volumes with AES 256-bit encryption
