The LaCie 18TB 1big Dock has been designed as an epicentre for 4K workflows. It combines an 18TB Seagate IronWolf Pro 7200 rpm SATA 3.5" hard drive that delivers data transfer speeds of up to 280 MB/s with two Thunderbolt 3 ports, a USB 3.0 Type-A port, a DisplayPort 1.4 output for 8K / 60 Hz, 4K / 120 Hz, 1080p, and 720p video, and SD and CompactFlash card slots. Operational temperatures will stay cool, thanks to an aluminium enclosure and thermoregulated fan.

While one of the Thunderbolt 3 ports is used to connect the 1big Dock to your compatible system running at least Windows 10 or macOS 10.12, the other can be used to daisy-chain up to six additional devices or provide up to 70W of charging power. In order to receive all 70W of charging power, your laptop must be plugged in using its power supply. Otherwise, you'll get 45W of power, or 30W if you're daisy-chaining multiple devices.

LaCie's 18TB 1big Dock includes a 40 Gb/s Thunderbolt 3 cable, a USB 3.0 cable, and an external power supply. Users will have access to LaCie's Toolkit software suite and will also be able to redeem a one-month membership to Adobe's Creative Cloud All Apps plan. If you ever need to remove the hard drive from the 1big, simply open the removable drawer.
