With the new LaCie Rugged, even if you take it into the field, your project stays on time. There’s no need to compromise on durability, mobility, and speed with IP 54-rated resistance to the elements and lightning-fast speeds through Thunderbolt and USB 3.0.

Get blindingly-fast transfer speeds on both Mac and PC with USB 3.0 and Thunderbolt interfaces. Back up and transfer huge quantities of data in a fraction of the time. Luxuriate in obviously more responsive photo library browsing. The LaCie Rugged, with the SSD version, delivers up to 387 MB/s – one of the fastest bus-powered products available on the market. The hard disk version delivers 4TB of storage and performs at up to 122 MB/s, a 35 per cent improvement over FireWire 800. 5400 RPM drives guarantee a minimum of 64MB of cache for premium performance and seek times.

There’s no need to allow your project to be derailed by incompatibility between an external drive and computer. The LaCie Rugged connects to any standard computer, anywhere with both USB 3.0 and Thunderbolt interfaces. It’s ideally suited to both your PC and Mac - since USB 3.0 is backward compatible. The integrated Thunderbolt cable has a storage space that is equal parts convenient and stylish when not in use, you’ll never lose it. The LaCie Rugged is also totally bus powered through its connecting cables. Its compactness and compatibility mean it’s the must-have sidekick to a new Mac or Ultrabook.

Data isn’t interchangeable, so it’s vital to shield it from any conceivable mishap, whether that’s on the road or in the studio. That's why the LaCie Rugged is MIL-compliant - data is protected even during accidental drops of up to two meters (6.6 feet). The removable cover can also be deployed during transit to provide IP 54-level protection against dust and water. When it comes to pressure, the LaCie Rugged can endure being run over by a one ton car. It’s sufficiently tough to be shipped for reliable delivery to clients or partners, and included software allows you to go one further and password protect your files with AES 256-bit encryption.
