LaCie 1big Dock

Centralize With an External Hard Drive Thunderbolt 3 Dock.

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.

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 restult? Your new creative headquarters.

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.

More-power 70W
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.
