Mac Mini M4/M4 Pro Docking Station

This Acasis docking station is built for Mac Mini M4 and M4 Pro users who need extra NVME storage and a DisplayPort output from a single USB-C connection. The aluminium chassis matches the Mac Mini aesthetic while housing two internal M.2 NVME bays. It draws up to 30 W of power delivery to run the SSDs and pass charge to the host. Professionals handling large media libraries gain a compact, desk-friendly expansion hub.

USB-C 40Gbps and DP 4K 144Hz Limits

The USB-C 40Gbps link carries both storage traffic and the DisplayPort 4K 144Hz video stream, so sustained SSD throughput will share bandwidth with the display signal. Driving a 4K panel at 144 Hz consumes a significant slice of the 40 Gbps pipe, leaving less headroom for simultaneous dual-SSD transfers. Users planning continuous heavy reads and writes while the external monitor is active should expect lower effective storage speeds than the interface maximum.

Upgrade From Single-Bay or Slower Hubs

This unit replaces a single-bay NVME enclosure or a lower-speed USB-C hub that lacks video output or power delivery. The jump is worthwhile when you need two NVME drives, a 4K 144Hz DisplayPort connection and 30 W pass-through charging all at once. If you only require one SSD, do not need DisplayPort, or already have a dedicated power supply, a simpler adapter avoids the extra cost and complexity.

Questions about this item

Should I choose one or two NVME drives for this dual-bay enclosure?

The enclosure has two M.2 NVME slots, so you can install one drive now and add a second later, or populate both bays immediately for maximum capacity.

What does the 40Gbps USB-C rating deliver when connected to a Mac Mini M4 or M4 Pro?

The 40Gbps USB-C link provides the full bandwidth ceiling for both NVME drives and the display output, so large file transfers and 4K 144Hz video run simultaneously without throttling.

How does the 30W Power Delivery interact with the Mac Mini and the installed SSDs?

The 30W PD input powers the two NVME drives and passes remaining current to the Mac Mini, reducing the need for a separate power adapter while the dock is in use.
