LaCie's popular d2 series of hard drives have been upgraded with Thunderbolt, in addition to the existing USB 3.0 ports. There is a 3TB model for $299 and a 4TB unit for $399, both coming with 3-year warranties.
LaCie promises top performance from the drives, though they are hampered a bit by the legacy hard drives inside. Solid state drives are needed to achieve the highest transfer speeds. That said, for those needing maximum storage, these drives should do the trick.
Deadlines rule our world. When digital storage is critical for your project, it had better be as fast and reliable as you are. In every office setting, it has to connect to any computer, deliver more than enough speed for the most demanding applications, and be completely reliable. Enter the LaCie d2 USB 3.0 Thunderbolt Series.
The drives are available from LaCie's online store.
