For context:

I’m copying the same files to the same USB drive for comparison from Windows and from my Fedora 41 Workstation.

Around 10k photos.

Windows PC: Dual Core AMD Athlon from 2009, 4GB RAM, old HDD, takes around 40min to copy the files to USB

Linux PC: 5800X3D, 64GB RAM, NVMe SSD, takes around 3h to copy the same files to the same USB stick

I’ve tried chagning from NTFS to exFAT but the same result. What can I do to improve this? It’s really annoying.

    As I’ve already mentioned, sync does absolutely nothing. The copy took so long that the sync command exited 4 times while the files were still transfering and were nowhere near finishing. Regarding the watch -d grep -e Dirty: -e Writeback: /proc/meminfo command, I did not mention it in this thread but I did try it and yes, there was some almost 900k kB of data in the “Dirty” buffer that went up and down constantly even after I’ve disabled the caching.
