7-in-1 Steam Deck Dock with M.2 Slot

This docking station combines video output, wired networking, power delivery, USB expansion and an internal M.2 drive slot in one compact hub. It connects to the host device through a single USB-C link and draws power from the supplied 100 W USB-C PD charger. The unit is compatible with Valve Steam Deck, Asus ROG Ally X and Legion Go handhelds.

Handheld gamers adding storage and desktop ports

The built-in M.2 slot accepts NVMe and SATA drives in 22x80, 22x60, 22x42 and 22x30 form factors, delivering up to 10 Gbps transfer speeds and 4 TB capacity. Users who only need video-out or extra USB-A ports without internal storage expansion may prefer a simpler adapter.

M.2 slot supporting NVMe and SATA up to 10 Gbps

The slot handles both NVMe and SATA protocols across the four listed lengths, enabling fast game-library expansion without an external enclosure. An SSD is not included, so buyers must supply their own drive to use this feature.
