Perhaps.  But, are you re-balancing your btrfs file systems regularly?

Doing it by hand was not practical for me.  I wrote a Perl script to 
automate the process.  On SSD's, the results were decent.  On USB flash 
drives, not so much.


Searching for a power tool today, I see:

2024-02-18 23:27:43 dpchrist@laalaa ~/stretch-amd64
$ apt-cache search btrfs | grep mainten
btrfsmaintenance - automate btrfs maintenance tasks on mountpoints or 
directories

https://packages.debian.org/bookworm/btrfsmaintenance


I suggest installing and trying the btrfsmaintenance package.
