Acasis 40Gbps Mac Mini M4 Dock Review: Comprehensive Expansion for Your M4 Mac Mini

The Acasis 40Gbps Mac Mini M4 Dock is a versatile accessory designed to enhance the connectivity and functionality of the M4 Mac Mini. This dock offers a range of ports, dual SSD slots, and utilizes Thunderbolt technology, providing a comprehensive solution for users seeking expanded capabilities.

Design and Assembly

The dock features a well-ventilated aluminum shell that encases the Mac Mini, ensuring efficient heat dissipation. Assembly is straightforward, with a Torx screwdriver included for convenience. The side panel houses two M.2 SSD slots, accompanied by thermal pads to maintain optimal operating temperatures. Users can easily install their own SSDs, apply the thermal pads, and secure the panel back in place. The Mac Mini is inserted from the bottom of the dock, and once positioned, the feet are reattached, providing a stable setup. A short cable connects any rear Thunderbolt port of the Mac Mini to the host port on the dock, facilitating seamless integration.

Ports and Connectivity

The Acasis dock is equipped with a variety of ports to accommodate diverse user needs:

– USB-A Ports: Three 10Gbps USB-A ports are available for connecting external drives, audio equipment, and peripherals. Each port supplies up to 4.5W of power, sufficient for devices like keyboards, mice, and external SSDs. However, for peripherals with higher power requirements, using external power sources is recommended.

– Display Outputs: Two DisplayPort outputs support up to 4K resolution at a 144Hz refresh rate with a single display connected, or dual 4K displays at 60Hz. Additionally, a third monitor can be connected directly through the Mac Mini’s HDMI or USB-C port as needed.

– SD/TF Card Slots: Located on the top of the unit, these slots support transfer speeds up to 312 megabytes per second, streamlining photo and video workflows. In testing, maximum speeds reached approximately 220 megabytes per second.

Notably, the dock’s design ensures that Wi-Fi performance remains unaffected, as the Mac Mini’s Wi-Fi antenna is positioned under a metal mesh that allows radio signals to pass through effectively.

Storage Capabilities

A standout feature of the Acasis dock is its dual M.2 SSD slots, each capable of 20Gbps speeds. These slots support various configurations, including RAID 0, RAID 1, JBOD, or single-drive setups, selectable via software. In RAID 0 configuration, the dock can achieve up to 40Gbps throughput, making it suitable for demanding tasks like 4K video editing and 3D rendering.

Performance testing revealed that, without displays connected, a pair of 1TB M.2 drives in RAID 0 achieved read and write speeds of approximately 2,400 megabytes per second. However, when dual monitors were connected via DisplayPort, speeds decreased to around 1,500 megabytes per second. This reduction is expected due to the bandwidth limitations inherent in a 40Gbps connection.

Considerations and Conclusion

For users who require the robust I/O capabilities of a Mac Studio but prefer the compact form factor of the M4 Mac Mini, the Acasis dock offers a compelling solution. It provides RAID storage, triple-display support, and extensive connectivity options, catering to professionals in video editing, design, streaming, and other fields that demand expanded functionality.

By utilizing a single Thunderbolt port, the dock delivers additional DisplayPort outputs, high-speed SSD access, an extra USB-C port, card readers, and three USB-A ports. While there is a minor tradeoff in bandwidth distribution under heavy dual-monitor and RAID usage, this is a reasonable compromise for most professional workflows.

Priced competitively, the Acasis 40Gbps Mac Mini M4 Dock offers a cost-effective upgrade, providing features that rival more expensive Thunderbolt docks, along with the added benefit of integrated storage slots. Its design is both functional and aesthetically pleasing, making it a suitable addition to any workspace or media setup.

Pros:

– Balanced cost and feature set

– Dual SSD slots

– Easy installation with included tools

Cons:

– Expected speed reductions under heavy I/O loads

– Design elements reminiscent of Mac Pro are non-removable

Rating: 4.5 out of 5

For users seeking an affordable yet feature-rich docking solution for the M4 Mac Mini, the Acasis 40Gbps Mac Mini M4 Dock stands out as a top-tier option. Its combination of extensive connectivity, storage expansion, and thoughtful design makes it a highly recommended accessory.
