Professional RAID Made Easy.

Whether you’re a seasoned creative pro or just getting started, the LaCie 2big family has something for everyone: a docking solution with an array of helpful ports and card slots; hardware RAID 0/1 for controlling speed, capacity, or data redundancy; huge capacity for archiving; smooth USB-C and Thunderbolt 3 speeds; Rescue Data Recovery services for long-term peace of mind; and enterprise-class drives dishing out intense performance so you can do what you do — better.

Our Most Powerful | 2big Dock Thunderbolt 3

Great innovation is often born from great challenge. 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 Thunderbolt 3 — a solution that gives back everything you need for a streamlined workflow.

USB 3.0 Hub

Via the front-facing hub, charge your phone or connect a shuttle drive or digital camera to offload footage and files.

Dual Thunderbolt 3 Ports

Daisy chain up to 5 additional LaCie 2big drives or other Thunderbolt or USB-C solutions.

SD and CF Card Slots

Directly ingest files from your drone, DSLR, GoPro^®, and other devices with the front-facing memory card slots.

DisplayPort

Connect to high-resolution 720-1080p and 4K displays.

USB 3.1 Port

Thunderbolt and Thunderbolt 2 Ready.

Using an older-gen Thunderbolt or Thunderbolt 2 Mac computer? You can still tap into the intense speeds of 2big Dock Thunderbolt 3 by using the Apple Thunderbolt 3 (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.

RAID 0

For PERFORMANCE

-Stripe Mode-

Drives are striped together and function like one large drive, enabling max speed and capacity.

RAID 1

For REDUNDANCY

-Mirror Mode-

Drives mirror each other, meaning data is automatically the same on both drives. If one fails, the other has your back.

JBOD

For FLEXIBILITY

-Just a Bunch of Disks-

Drives function independently, offering two separate drives in one enclosure.

Fierce Internal Hard Drives.
