LaCie 2big External HDD Overview

If you've been looking for a powerful and versatile Thunderbolt 3 docking station that restores many of the ports and connectivity that have been removed on modern day laptops, take a look at the 20TB 2big Dock 2-Bay Thunderbolt 3 RAID Array from LaCie. The 2big Thunderbolt 3 Dock delivers a storage capacity of 20TB, which is comprised of two 10TB Seagate IronWolf Pro 7200 rpm SATA III 3.5" enterprise-class hard drives. The 2big comes formatted as exFAT, meaning it will work with both Windows and Mac systems right out of the box, and is configured as hardware-controlled RAID 0, which provides performance gains, but no data redundancy. Also supported is RAID 1 and JBOD. Each of the two 3.5" SATA III drive bays are hot-swappable, allowing users to remove and replace failed hard drives.

The back of the 2big is equipped with two 40 Gb/s Thunderbolt 3 ports, which allow you to interface with your host system at speeds up to 550 MB/s. The Thunderbolt 3 interface can also provide up to 45W of power to connected devices and may be used to daisy-chain up to five additional Thunderbolt 3 peripherals, including displays, or one USB-C peripheral. Between the second Thunderbolt 3 port and the DisplayPort 1.4 interface, the 2big supports two 4K displays or one 8K display.

On its front, the 2big has a built-in USB-A 3.2 Gen 2 port, which can charge your USB device or connect a USB drive or digital camera for offloading files. Also available are dedicated CFexpress Type B, CFast 2.0, and UHS-II SDXC card slots, allowing you to directly download content from your drone, DSLR, GoPro, and more. This dock can store hundreds of hours of 4K footage and hundreds of thousands of raw images.

The LaCie 2big Thunderbolt 3 Dock includes a Thunderbolt 3 cable and an external power supply. Protection is provided by a limited 5-year warranty.

Please note that Thunderbolt and Thunderbolt 2 are only supported when Apple's Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter is used with systems running macOS 10.12 Sierra or later. Also, the CFexpress Type B reader doesn't work with XQD media.
