Does KDE makes file transfers between hard drives slower? My laptop is too slow when copying files to my usb flash drive. (programming.dev)

I have two laptops, I'll call them laptop 1 and laptop 2.

Laptop 1 is my gaming laptop, and laptop 2 is a very low-spec one that I use as a jellyfin server. Here's the neofetch result for both of them:

Laptop 1

Laptop 2

The problem

On both of them, I copied a 5GB folder from the laptop to my 3.0 usb flash drive, I used this rsync command on each:

rsync -a --progress folder_path destination_folder_path

Laptop	Average transfer speed
Laptop 1	9MB/s
Laptop 2	45MB/s

How is this possible? The Laptop 1 is way superior than laptop 2. The laptop 1 has an nvme SSD while laptop 2 has an old 320GB HDD, yet the transfer speed difference is insane.

Does KDE affect the folder copying somehow? If I copy a file on the same SSD on laptop 1, the speed reaches more than 400MB/s.

What is going on here?

My guess is that laptop 1 is connected to the HD through USB2 not USB3. Or u r using USB hub

I'm not using a USB hub. How can I confirm that the usb port is indeed a 3.0 one? Is the color blue of the port enough?

USB 3.0 has additional contacts.
