LaCie 4TB 1big Dock USB3.1 Thunderbolt External Hard Drive

Laptops today are powerful and portable, but their slim build means fewer ports and memory card slots — and therefore more dongles. The LaCie 1big Dock is here, not only to help you safely store and back up loads of footage, but to charge your phone and USB devices, let you offload files, connect pro 4K monitors, and power your laptop. All through a single cable that leads from your drive to your laptop and dishes out incredible Thunderbolt™ 3 performance.

SD and CF Card Readers, Ports, and More.

Directly ingest footage, charge devices, connect 4K monitors, daisy chain additional drives, and store your portfolio — that’s the magic of 1big Dock. But what’s more, you get powerful Thunderbolt 3 performance and the reliability of a Seagate IronWolf Pro enterprise-class hard drive. The result? Your new creative headquarters.

Brilliant. From Start to Finish. – Our plan was to build a solution so refined, so centralised, that you could freely focus on what matters most: creating awesome work. 

SD and CF Card Readers – Directly ingest files from your drone, DSLR, GoPro®, and other devices with the front-facing SD card reader and CF card reader. (CF/SD cards sold separately.) 

USB 3.0 Hub – Charge your phone, offload content from USB devices like shuttle drives and digital cameras, or simply connect USB peripherals. 

DisplayPort 1.4 – Directly connect to your display monitor — from 720-1080p up to 4K 120Hz, or even 8K 60Hz. 

Dual Thunderbolt 3 Ports – Daisy chain up to six additional storage devices, plus charge your Thunderbolt, USB-C, or USB 3.0 laptop. 

Swappable Drawer With Hard Drive – Need to maintain or upgrade your hard drive? Simply use the removable drawer and swap in a new drive anytime. 

Self-Cooling Aluminium Enclosure – 1big Dock’s aluminium enclosure and thermoregulated fan deliver sustained, optimised reliability and performance for the long haul. More Power to You. And Your Laptop.

1big Dock is engineered to keep your laptop charged thanks to its patent-pending power pass-through feature.

Power Pass-Through

Simply connect your laptop’s power supply to 1big Dock’s Thunderbolt 3 daisy chain port for up to 70W of power delivery.

Power Delivery

When not using your charger, you’ll still get up to 45W of power from 1big (up to 30W if you’re simultaneously daisy chaining other USB-C devices). Either way, 1big keeps you going when you’re knee-deep in the creative process. 

A Fierce Hard Drive for Intensive Projects.

A Seagate IronWolf Pro enterprise-class drive lives inside 1big Dock — and it’s the secret sauce to sprinting past goals and deadlines. Supporting up to 300 TB/year workloads, this powerhouse HDD is specifically designed for high-speed 7,200 RPM performance, smooth power management, massive capacity and 24×7 reliability. And for ultimate peace of mind it’s covered by a five-year warranty.
