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?
USB 3.0 has additional contacts.
