M2 Pro Mini thunderbolt ports speed

[Bromden]

I have a M2 Pro Mini connected to a Studio Display.

Samsung T5 external SSD.

When connected to the Studio Display usb-c ports, I get 500 write / 520 read speeds.

When connected to the Mini’s thunderbolt 4/usb-c ports, I get 430 write / 390 read speeds.

Anyone knows if this is a normal behavior?

Thank you.

This is intriguing! I'm also interested in this...

What speed differences do we get with other external ssds?
