Questions about this item

What is the practical data-transfer ceiling of the 10 Gbps USB 3.1 ports?

The four USB 3.1 ports each deliver up to 10 Gbps, so external SSDs and high-speed peripherals can saturate that bandwidth in real use.

Which ThinkPad models fit the proprietary side connector on this dock?

The side connector is designed exclusively for compatible ThinkPad notebooks; check your laptop’s spec sheet for the matching Ultra Dock interface.

How do you secure the dock to the desk so it cannot be lifted away?

Use the optional master-key lock slot on the chassis to anchor the dock with a cable lock; the mechanical unlock lever then releases only the laptop.
