Compact silver aluminium dock with multiple ports and a power button

D-Link

D-Link DUF-901 9-in-1 USB4 Docking Station

SKU CH-2J78-84X8E

A 9-in-1 USB4 dock adds dual DisplayPort 1.4 outputs, 2.5 GbE, four 10 Gbps USB ports and 100 W charging through one 40 Gbps link

  • Connect up to 9 devices through a single USB4 port
  • Transfer data at up to 40 Gbps via the USB-C 40 Gbps port
  • Drive two displays simultaneously with dual DisplayPort 1.4 outputs
  • Wired networking at 2.5 GbE for fast, stable connections
  • One-touch power button resets all connected ports instantly

One cable nine devices

The D-Link DUF-901 turns a single USB4 port into nine connections. It adds two DisplayPort 1.4 outputs, 2.5 GbE networking, four high-speed USB ports and a legacy USB-A port. The compact aluminium body fits a mobile workstation or a permanent desk setup. A central power button resets every attached peripheral at once.

Bandwidth and display limits

USB4 provides up to 40 Gbps of total throughput shared across all active ports. Dual 8K output depends on host GPU support for DisplayPort 1.4 and available link bandwidth. The 2.5 GbE port reaches its rated speed only when the network infrastructure matches. Power delivery reaches 100 W if the host and cable both support that level.

Replaces a tangle of dongles

One hub removes the need for separate video adapters, a network dongle and multiple USB hubs. The jump is worth it when you regularly connect external NVMe storage, dual monitors and wired Ethernet together. Buyers who only need a single extra screen or occasional file transfers may not use the full port set.

Highlights

  • Connect up to 9 devices through a single USB4 port
  • Transfer data at up to 40 Gbps via the USB-C 40 Gbps port
  • Drive two displays simultaneously with dual DisplayPort 1.4 outputs
  • Wired networking at 2.5 GbE for fast, stable connections
  • One-touch power button resets all connected ports instantly

Questions about this item

Should I pick the 40 Gbps USB-C port or the 10 Gbps USB-C port for my fastest external NVMe drive?

Use the single USB-C port rated at 40 Gbps for the highest throughput with external NVMe SSDs or RAID enclosures; the second USB-C port tops out at 10 Gbps and is better suited for peripherals that do not need peak bandwidth.

What does the 40 Gbps headline speed actually deliver when I plug the dock into my laptop?

The 40 Gbps figure is the USB4 interface ceiling; real-world transfer rates depend on your laptop's USB4 implementation, the drive's own speed, and cable quality, so expect somewhat lower sustained throughput in everyday use.

Which DisplayPort standard do the two video outputs use, and what resolution ceiling does that impose?

Both video outputs are DP 1.4, enabling dual 8K or quad 4K display configurations within the bandwidth limits of that standard and your host's graphics capability.
