Great innovation is often

Great innovation is often born from great challenges. So, when modern USB-C laptops eliminated many of the ports and slots crucial to the creative process, we went straight to the drawing board. The result is 2big Dock — a Thunderbolt solution that features modern media card slots for ultra-streamlined workflows.

  • USB 3.2 Gen2 Hub
  • Via the front-facing hub, charge your phone or connect a shuttle drive or camera to offload footage and files.
  • CFexpress Type B, CFast 2.0, and SD Card Slots
  • Directly ingest files from your camera, drone and other devices with the front-facing advanced memory card slots.
  • Dual Thunderbolt Ports
  • Daisy chain up to five additional Thunderbolt devices or one USB-C device.
  • DisplayPort 1.4
  • Connect an 8K (30 Hz) or 4K (120 Hz) monitor via the DisplayPort.

Thunderbolt 2 Ready.

Using an older-gen Thunderbolt 2 Mac computer? You can still tap into the intense speeds of 2big Dock by using the Apple Thunderbolt (USB-C) to Thunderbolt 2 Adapter.*

Hardware RAID. Simplified

Whether you’re new to 2-bay hardware RAID or a seasoned pro, LaCie RAID Manager makes it easy to configure any 2big for speed, capacity, or data redundancy. It even helps you monitor the system’s health via email notifications.


For PERFORMANCE – Stripe Mode
Drives are striped together and function like one large drive, enabling max speed and capacity.


For REDUNDANCY – Mirror Mode
Drives mirror each other, meaning data is always the same on both drives. If one fails, the other has your back.


For FLEXIBILITY – Just a Bunch of Disks
Drives function independently, offering two separate drives in one enclosure.

Fierce Internal Hard Drives.

IronWolf Pro enterprise-class drives live inside our latest-gen 2big solutions — and they’re the secret ingredient to sprinting past goals and deadlines. Supporting up to 300 TB/year workloads, they’re specifically designed for RAID and high-speed 7,200 RPM performance, delivering smooth power management, massive capacity, and 24×7 reliability. And for ultimate peace of mind, they’re covered by a 5-year warranty.

We’ve Got Your Back
