Storage for the 4k era

Thanks to its Thunderbolt 2 technology, the LaCie 5big delivers incredible, sustained speeds of up to 1050 MB/s. This is enough bandwidth to edit several video streams in native 4K resolution. With this kind of speed, videographers working in Apple® Final Cut Pro® or Adobe® Premiere® get maximum quality from footage and see native 4K edits in real time.

RAID for speed with security

The LaCie 5big offers a range of RAID modes that allow users to tailor the product to their needs. Its hardware RAID delivers sustained performance, better flexibility and the ability to connect the product to another computer while keeping the RAID configuration.

RAID modes 5 and 6 provide complete data protection against disk failure, while providing excellent speed and capacity. These features make the LaCie 5big an ideal solution for users that want to use a single storage product for both video editing and backup. In protected RAID modes, even in the case of disk failure, the LaCie 5big’s hot-swappable disks mean zero data loss or downtime.

Dual thunderbolt ports

The LaCie 5big features two Thunderbolt 2 ports for daisy chaining. Professionals can daisy chain up to six Thunderbolt devices to a computer via a single cable (included). Thunderbolt 2 is also backward compatible, using the same cables and connectors as first-generation Thunderbolt** devices and computers. Professionals can now create a plug and play 4K video editing environment with increased capacity, incredible speed and convenience to their workflow.

Advanced cooling and long-term reliability

The LaCie 5big's cutting-edge cooling system ensures long-term reliability by preventing overheating. The system consists of three key components: an innovative heat-dissipating aluminium casing, a Noctua® cooling fan, and jumbo heat exhausts. The ultra-quiet Noctua NF-P12 fan pulls heat away from the internal components while producing very little noise. Altogether, this professional cooling system makes the LaCie 5big incredibly reliable and perfect for even the most noise-sensitive creative environments. Additionally, the 5big casing is made from a seamless aluminium cast, acting as armour to protect internal components.


The LaCie 5big Thunderbolt 2 featuring Enterprise Class hard disks will be available this quarter in 40 TB capacity through the LaCie online store and LaCie resellers.


The LaCie 5big with Enterprise Class disks comes with a five-year warranty that covers drives, enclosure, and spare parts, ensuring a solid long-term investment. The warranty includes complimentary web-based resources, expert in-house technical support and worldwide repair and/or replacement coverage.
