Q&A

  • Question 1: Why doesn't the iPhone 15 Pro Max recognize the Thunderbolt enclosure?
    Answer: The iPhone 15 Pro Max may not provide enough power for direct connection. Solutions: 1. Use a 10Gbps data cable (Thunderbolt 3/4 cables are not supported). 2. Connect via a powered docking station.
  • Question 2: How does the TBU405ProM1 fan work?
    Answer: The fan is controlled via a switch: 1. Press the switch after connecting to start the fan. 2. Press it again to turn off the fan.
  • Question 3: Why is my SSD's write speed much slower than its read speed on Windows?
    Answer: Enable write caching for improved performance:

1. Go to **Device Manager > Disk Drives > Select SSD > Properties > Policies** and enable write caching.

2. Under **Disk Management**, select the SSD, open **Properties > Strategy**, and enable "Better Performance" with write caching.

3. Ensure AHCI mode is enabled and the Intel RST driver is installed.

4. If issues persist, test on another computer.

So far, so good...

Only been using it a few weeks but seems really stable and fast and was definitely the most affordable / reliable solution I could find.

I’m marking down to 4 stars as it would be great for the enclosure fan to be automatic as and when needed, as well as manually activated. Fan noise isn’t too loud when on though (but definitely audible) which is a plus and imagine you only need it when it’s doing some heavy work. Absolutelsilence when it’s off though.

Also, you need to be careful not to move it when in use as it will lose connection - just something to be aware of. But definitely recommend.
