For 4K and other bandwidth-hungry workflows, external storage needs to be fast, secure, reliable, and quiet.

The LaCie 5big 20TB Thunderbolt 2 fits the bill, delivering Thunderbolt 2 speeds for 4K video editing, 20TB capacity, and hardware RAID 5/6 for no-compromise data security.

Thunderbolt 2 Speeds for the 4K Era

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 5x 7200RPM disks and the result is incredible. Turbocharge 4K workflows, file transfers, and backups.

LaCie RAID for Speed with Security

Supported RAID Levels

The LaCie 5big offers RAID modes 0, 1, 5, 6, 10, and JBOD. Its hardware RAID controller delivers sustained performance, better flexibility, and the ability to connect the product to another computer while keeping the RAID configuration.

The LaCie 5big is pre-configured in HFS+ and RAID 5, so ready to use straight away out of the box for Mac users. The RAID mode can be re-configured to suit your needs using the LaCie RAID Manager utility. The LaCie 5big can also be easily reformatted for use on Windows systems.

RAID 5/6 for data protection

RAID modes 5 and 6 provide complete data protection against disk failure, while providing excellent speed and capacity. This is perfect for when you want to use a single storage product for both editing and backup. Even in the case of disk failure, the LaCie 5big’s hot-swappable disks mean zero data loss or downtime.

RAID 0 for Performance

You could instead choose RAID 0 to maximize speed and capacity for current projects, and then move completed projects to archival storage incredibly quickly.


Or, choose JBOD, which allows you to see and use each disk independently. With five working days a week, you can assign each disk to a daily backup. It’s even possible to set up multiple RAID volumes. For example, create both a 3-disk RAID 5 array for current projects, and a 2-disk RAID 1 array for backing up source files and final footage.
