The LaCie 12TB 6big 6-Bay Thunderbolt 3 RAID Array is a 6-bay storage enclosure complete with a storage capacity perfect for storing large files such as 4K video, RAW photos, and much more.The 6big delivers speeds up to 2600 MB/s, RAID 5/6 with two Thunderbolt 3 ports for fast file transfers and performance.

The absolute fastest I/O.

For the 6big and 12big, LaCie harnessed the breakthrough performance potential of the Thunderbolt 3 I/O and squeezed the absolute best speeds out of the hard drives. We added a hardware RAID controller and 7200RPM drives, and the result is astonishing 12big speeds of up to 2600MB/s—and 2400MB/s in RAID 5.

For lightning-fast video workflows.

That kind of speed can slash time off nearly every task in your post-production workflow. Ingest hours of RAW footage from a Blackmagic® cinema camera into Adobe® Premiere® Pro in a fraction of the time. Then edit multiple streams of ProRes 422 (HQ), ProRes 4444 XQ, as well as uncompressed HD 10-bit and 12-bit video. For big projects packed with high-def clips, thumbnail and preview rendering becomes much more responsive.

And for your smartest workspace.

With double the video bandwidth of its predecessor, Thunderbolt 3 lets you daisy chain dual 4K displays or a single 5K display to the LaCie 12big or 6big. With two 4K displays, you can spread out your workspace by dedicating one display to your timeline and the other to previewing 4K footage, for example. It's even possible to power a compatible laptop through the Thunderbolt 3 connection.

Compatible with Thunderbolt and Thunderbolt 2

It’s possible to connect the 6big and 12big to devices with previous generations of Thunderbolt. Just use a Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter (sold separately).

Bigger in every way. Except in footprint.

With up to 120TB (12big) or 60TB (6big) on your desktop, you can safely store massive amounts of ultra hi-res footage.

Compact Footprint

Get massive capacity on your desktop in a footprint that’s smaller than an iPad Air® (59 vs 62 in2).

Front-accessible drives

Conveniently and quickly remove and replace drives from the front of the product. Keep track of drive health and RAID build status with the front-facing drive status LEDs.
