I recall a long and detailed discussion on this list before F33 was
released concerning what disk maintenance would be required with BTRFS.
As I recall, the final word was along the lines the running Scrub and
the other BTRFS utilities wouldn't be necessary since it was being set
up so maintenance shouldn't be needed. There was also some hesitancy to
call for running scrub because, depending on how often it's run Scrub
can be hard on SSDs (they wear out faster).

From what I can tell scrubbing only reads data and compares to the stored checksum. Why would that wear out a SSD?

Thanks,
