LaCie (www.lacie.com) has announced the US$449.99 Rugged RAID, the latest product to join its line of Rugged mobile hard drives. It features twice the speed and capacity of a standard mobile hard drive.

According to the folks at LaCie, the Rugged RAID is also the only product in its class to feature hardware RAID 0 and 1, which lets professionals optimize the product for speed or data security according to their workflow – and use it on any Mac or PC. It features Thunderbolt and USB 3.0 along with two internal hard drives that are preconfigured in hardware RAID 0 for sustained performance of up to 240 MB/s.

The LaCie Rugged addresses sports 4TB in a compact footprint. It features RAID 1 (mirrored mode), which is where the data is duplicated across the two drives.
