Pros trust Rugged drives
With the LaCie Rugged RAID, you get it all in one package — with zero tradeoffs. It delivers a game-changing blend of PC and Mac compatibility, capacity, speed, mobility, and reliability. 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 Waiting
When 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 Computer
Tailor the LaCie Rugged to your precise needs. Leave it in RAID 0 (striped mode) to maximize speed and capacity. Or choose RAID 1 (mirrored mode), where your data is duplicated across the two drives. So even if a drive fails in the field, your files remain completely accessible. 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.
Innovative Design for True Mobility
LaCie has designed acclaimed Rugged storage products for nearly a decade. With the Rugged RAID, LaCie makes your data more mobile than ever. Carry fewer hard drives, fewer cables, and encounter zero roadblocks.

Rugged Design — The LaCie Rugged is tested to withstand drops** of up to 1.5 meters (5 feet) and being run over by a 1-ton car. So whether the LaCie Rugged falls out of your backpack or is crushed by stacks of suitcases in the airplane cargo hold, your data remains safe.

Protective Cap — With its cap in place, the LaCie Rugged is IP 54-rated for superior resistance to dust and water splashing — even during operation. So even during a dust storm or tropical downpour, you stay confident that your data remains accessible.

Massive Capacity, Compact Footprint — With 4 TB in a portable size, the LaCie Rugged can store the equivalent of thirty 128 GB memory cards. Capacity finally meets mobility.

Integrated Thunderbolt Cable — Ensure you never lose your cable, stow it neatly when not in use, while saving space in your luggage.

No Power Cable Needed — Powered through the Thunderbolt cable, the LaCie Rugged lets you access your data anywhere — no power outlet required.

Hardware RAID — The LaCie Rugged's RAID system is operating system independent, so any computer recognizes it.
