With the redesigned 2big, instead of aiming for incremental, LaCie shot for revolutionary. Its all-new industrial design demolishes the status quo and sets a new standard for versatility and reliability. The LaCie 2big also features unbeatable Thunderbolt 2 technology and hardware RAID for sensational performance.

Thunderbolt 2 Speeds for the 4K Era
With Thunderbolt 2 technology, the interface is no longer the performance bottleneck. For the 2big, LaCie harnessed the breakthrough performance potential of the Thunderbolt 2 I/O, squeezing the absolute best speeds out of the hard disks. Add a hardware RAID controller and 7200RPM disks and the result is incredible, sustained speeds of up to 420MB/s that turbocharge file transfers and backups.

With this kind of speed, videographers can edit multiple 2K uncompressed 10-bit streams or play back compressed 4K video. Digital photographers can browse a massive RAW photo library with zero lag. And, thanks to support for DisplayPort 1.2, it's now possible to daisy chain higher-resolution displays such as 4K monitors.
