seagate enterprise classEnterprise Class!

The LaCie 12big Thunderbolt 3 contains 12 x Enterprise Class Hard Drives, for superb accessibility, reliability, and robust performance.

Enterprise Class Hard Drives are designed to operate 24×7 on 16-bay racks (instead of 8×5 operations for traditional hard drives) and are rated for 8760 hours of operation per year for extraordinary availability.

High Capacity Storage

The LaCie 12big Thunderbolt 3 is ideal for storing large amounts of digital media and is available in the following capacities:

  • 48TB Enterprise Class (pn: STFJ48000400)
  • 72TB Enterprise Class (pn: STFJ72000400)
  • 96TB Enterprise Class (pn: STFJ96000400)
  • 120TB Enterprise Class (pn: STFJ120000400)
  • 168TB Enterprise Class (pn: STFJ168000400)

LaCie 12big Interface options

The LaCie 12big has adopted the latest Thunderbolt 3 interface (x2) featured on all the latest Apple MAC computers. As well as Thunderbolt 3 the 12big has a single USB 3.1 port Type-C.

Backwards Compatible USB 

USB 3.1 Type-C is backwards compatible to USB 3.0 and USB 2.0 by using the USB Type-C to USB Type-A cable. Therefore unlike other 12-Bay RAID hard drives in the market place the 12big can connect to pretty much any USB computer (providing the minimum OS requirement is met)! Ideal if you do not have the Thunderbolt connection on your computer.

Lighting Fast Speeds

Thunderbolt 3 along with the hardware RAID and 7200rpm drives will provide superior read/write speeds of 2600MB/s in RAID 0 and 2400MB/s in RAID 5. Ideal for editing and streaming 4k and 6k video.

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.

Performance Benchmark

Thunderbolt 3 (reads | writes in MB/s):
12big RAID 0: 2600 | 1700
12big RAID 5: 2400 | 1200

USB 3.1 (reads | writes in MB/s):
12big RAID 0: 400 | 400
12big RAID 5: 350 | 350

For big projects packed with high-def clips, thumbnail and preview rendering becomes much more responsive.

Daisy Chain with Thunderbolt 3

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.

With two 4K displays, you can spread out your work space 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.

12big Supported RAID Levels

Speed / RAID 0

Choose RAID 0 for maximum capacity and speed. Ideal for editing and multi-streaming 4k video.

Speed > Security / RAID 5

Choose RAID 5 for speed and security. RAID 5 allows one drive to fail and the 12big will stay online.

Security > Speed / RAID 6

RAID 6 will reduce the overall performance (read/write speed) of the unit but allow up to two drives to fail and it will stay online. Ideal for use as high capacity redundant storage system.

5 Year Warranty

The LaCie 12big comes with a 5 year limited warranty which covers drives, the enclosure, and spare parts. Technical support is also available via phone or email.
