Btw, I should also add here: it may be clear t
I see no one mentined yet: BTRFS is slow on HDDs. It trivially comes from BTRFS
being COW. So if you changed a bit in a file, BTRFS will copy a block (or maybe
a number of them, not sure this detail matters) to another place, and now your
data got fragmented. SSDs may not care, HDDs on the other ha
