Hey guys.
Thanks for your comments. I am clueless what's going on. I did a little more testing with my Pi's. So far I only tested read-speed on the SSD's with Hdparm. Now I did write tests with dd, and with any combination of my 256GB Adata SSD, 1TB Samsung SSD, 4TB TeamGroup SSD and the Pineberry or Pimoroni SSD hat, I get 42-45MB/s for all of them. How does that makes sense??? Of course that kinda explains why I can't obtain more than 20MB/s write speed to the Pi via my home ethernet. I also made the write tests on both of my Pi 5's. So it seems like a systematic error on... what? Any SSD of mine or both Pi 5's??
What do you think?
