Copying a large file from an USB 3 disk (NTFS or EXT4) to another one (UFS/FreeBSD) is a very slow process....

Hello to everyone.

I'm copying a large file from a NTFS formatted disk to another
one,UFS/FreeBSD disk,both are removable disks attached to the USB 3 port.
The file is 200 GB large and it is copied very slowly. Why it is so slow ?
I don't know where to store my virtual machines. I tried to save them on
the ext4 disk because I wanted to share them easily between Linux and
FreeBSD but I've realized that when I mount the disk in FreeBSD after some
time it corrupts. I tried to store it on the NTFS disk but it happens the
same. So,now I'm on FreeBSD and I'm copying them to a dedicated UFS/FreeBSD
style disk,but as I said,the speed is very slow. How can I increase the
speed ?. Actually I'm using this command,because I want to resume the
uploading if it breaks at some point :


root@marietto:/mnt/da3p2/bhyve/Ubuntu # rsync -avAXEWSlHh
/mnt/da0p1/Backups/OS/bhyve/Ubuntu/im* . --no-compress --info=progress2

sending incremental file list
impish-cuda-11-4-nvidia-470.img

2.13M 0% 9.49kB/s 6284:55:38


and : where do you save large files ? what's the procedure that you use to
copy large files with a decent speed ? Unfortunately under Linux is not
safe to use a RW ufs disk access. So,I'm out of solutions.
