LaCie’s 2big surpasses what the market has come to expect from high speed desktop storage by aiming for, and achieving, a ground breaking redesign. A mechanised overhaul sets new benchmarks for consistency and adaptability. The LaCie 2big also provides premium performance thanks to Thunderbolt 2 technology and RAID hardware, and 8TB of storage.

It’s no longer that case that an interface is the debarring factor in a storage solution’s speed, thanks to Thunderbolt 2 technology. LaCie have succeeded in pressing the absolute best speeds out of its hard disks because the 2big capitalises on the Thunderbolt 2 I/O’s breakthrough performance potential. Continuous speeds of up to 420 MB/s, capable of turbocharging file transfers and backups, are possible with the simple hardware additions of a RAID controller and 7200 RPM disks. The unit can run RAID 0 (FAST), 1 (SAFE) and JBOD.

A Digital photographer can enjoy seamless perusal of a massive RAW photo library with zero lag. Videographers re empowered to edit multiple 2K uncompressed 10-bit streams, or play back compressed 4K video with this kind of speed. Daisy chaining higher-resolution displays, like 4K monitors, is also now a possibility.

The LaCie 2big achieves top-line speeds on any late-model PC or Mac with USB 3.0 and Thunderbolt 2 interfaces. USB 3.0 backward compatibility makes it possible to connect the LaCie 2big to any standard PC. You can seamlessly connect to both PC and Mac computers without losing your RAID configuration, with support for exFAT and built-in hardware RAID. Whatever your workstation, move mountains of data – fast. Included LaCie Private-Public software also enables AES 256-bit encryption to password-protect volumes.
