I get only 10Gb/s when I connect the USB kable provided by Samsung. Is the Thunderbolt/USB4-buss compatible with the Samsung provided cable (supports USB 3.2Gen 2x2 (20 Gb/s))
Mac Mini Pro 2023 16GB/1TB

The MacMini only supports single lane USB 3.x and not dual lane (what the 2x2 means isn the Samsung spec) and therefore will only get 10 Gb/s connection. The Thunderbolt 4/USB 4 specs only require that single lane USB 3.x be supported. Supporting dual lane is optional.
If you need or want faster speeds, you will need to get a Thunderbolt 3 or 4 drive or a USB4 drive both of which support up to 40 Gb/s.

You could try a TB cable. Most Macs support either 3.2(10gbps) or 40 if using a TB drive and nothing in between.
Thank you, I will have to accept 10Gb/s on ny Mac Mini Pro 2023. Some money lost in buying a Samsung T9 instead of T7, next time I will find out before.
