For 4K and other bandwidth hungry workflows, external storage needs to be fast, secure, reliable, and quiet. The new LaCie 5big fits the bill, delivering Thunderbolt 2 speeds for 4K video editing, up to 40TB capacity, and hardware RAID 5/6 for no compromise data security. With Thunderbolt 2 technology, the interface is no longer the performance bottleneck. For the 5big, 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 7200 RPM disks and the result is incredible, sustained speeds of up to 1050 MB/s that turbocharge 4K workflows, file transfers, and backups. The 40TB version Seagate Enterprise Class hard disks that provide superb accessibility, reliability, and robust performance. Designed to operate 24x7 on 16 bay racks (instead of 8x5 operations for traditional hard drives), these HDDs can support 8,760 hours of operation per year for extraordinary availability.
