The LaCie 1big Dock Thunderbolt 3 is a powerful docking station that allows you to safely store and backup hours of footage. As laptops become more portable with a slim build, they can no longer facilitate additional ports and memory card slots. LaCie 1big Dock is the all-in-one docking station - equipped with SD and CF card readers as well as ports - that lies at the heart of your workflow. It can charge your smartphone and other USB devices, offload files, power your laptop and connect pro 4K monitors - all with a single cable connection and the power of Thunderbolt 3.
