Thunderbolt 5 vs Thunderbolt 4 External USB4 SSD Speed Test Comparison M4 Mac Mini vs M4 Max MacBook
139Thunderbolt 4 vs Thunderbolt 5 on M4 Mac using the same fast USB4 external SSD.
So this is a test of the same USB4 SSD, which is a Zike 40Gb/s USB4 enclosure with a Samsung 990 Pro 4TB SSD inside of it. Being tested with Thunderbolt 5 socket on an M4 Max MacBook Pro and Thunderbolt 4 on a base M4 Mac mini.
While the Zike enclosure is USB4, USB4 and Thunderbolt 4 share the same data protocols and when used with a Thunderbolt host computer, USB4 will act as Thunderbolt 4 as far as data bandwidth is concerned.
Now don't forget, both of these Macs are also USB4 compatible, due to the interchangeability of USB4 and Thunderbolt. So both Macs are fully compliant with the Zike enclosure.
Like I said in the video, I don't know the reason for the difference. However, if I had to guess I would say that the internal SSDs of the M4 and M4 Mac Macs are having an effect. I'm guessing that both Macs are caching using their internal SSDs and with the SSD on the M4 Mac mini being a lot slower than the SSD on the M4 Max MacBook Pro. This could maybe explain the difference but that's just a guess.
Anyway. Do you know the answer? Or do you have any thoughts on why there's a difference? If so, please let me know in the comments.

My recommendation for a fast Thunderbolt 4 USB4 external SSD is the Acasis TBU405Pro M1 enclosure, paired up with the WD SN850X SSD. I use the 4TB version and it's awesome. This combination does not thermal throttle as the Acasis enclosure is fan cooled and keep the WD SN850X below its thermal throttling point.

I have not thoroughly tested the 990 Pro with all of my enclosures. However, this is an excellent SSD if used internally with a computer with proper SSD cooling and good airflow. While I can't recommend the 990 Pro just yet for any use with any enclosure, here's some links for anyone who is going to use it in a properly cooled computer.
