LaCie 4TB d2 Thunderbolt 2 & USB 3.0

The new LaCie d2 combines best-in-class interfaces with a Seagate 7200 RPM hard disk, resulting in stunning speeds of up to 180 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.

Unibody Enclosure

The casing is forged from a single sheet of aluminum, providing uncommon rigidity for long-term durability and premium quality.

Power-Saving Mode

For Thunderbolt connections, save energy by pressing the power button to spin down disks without interrupting daisy chain transfers. For USB connections, disk spins down automatically when the host operating system goes to sleep.

Fan-Free Cooling

The seamless, all-aluminum unibody enclosure draws heat away from the hard disk. The integrated base extends the enclosure's surface area, providing even more space for heat dissipation. The results are a long lifespan for components and ultra-quiet operation.

Integrated Cable Management

Built-in cable management prevents accidentally disconnected interface or power cables without compromising the look and design of the product.

Anti-Vibration Features

A cushioning base and vibration-absorbing hard disk mounts combine to dramatically reduce vibration.

Optional External Hybrid Storage Upgrade

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 128 GB 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.
