As the ultimate solution for on-the-go professionals, the LaCie Rugged adapts to your needs for performance or complete data security. More Speed, Less WaitingWhen getting the win hinges on speed, you need Thunderbolt - the fastest interface on the market. The LaCie Rugged also includes two internal hard drives that are preconfigured in hardware RAID 0 for sustained performance of up to 240 MB/s. At this speed, you can store and transfer content twice as fast as before. It's a time-slashing solution for field-based professionals who collect and move tons of data onto external storage. Versatility Anywhere, on Any ComputerTailor the LaCie Rugged to your precise needs. Leave it in RAID 0 (striped mode) to maximize speed and capacity.

Using LaCie Setup Assistant, it's incredibly easy to make the LaCie Rugged compatible with any Mac computer, PC, or both. And with Thunderbolt and USB 3.0 interfaces and hardware RAID, any computer will recognize the LaCie Rugged. It lets you transport a massive amount of data - with complete security - and access it freely from any computer.
