=== Mount options ===

The default mount settings chosen by btrfs are really optimal in most cases! There are only a few options to think about. Current and accurate information can also be found at: https://btrfs.readthedocs.io/en/latest/Administration.html

* '',discard'' ('''automatic !)'''

* '',ssd'' ('''automatic !)'''

* '',space_cache'' ('''automatic !)'''

* ''''',compress=zstd:7'''''

Enables automatic and transparent compression in the file system. If compression is enabled, nodatacow and nodatasum are disabled.

Btrfs makes the compression level adjustable, with higher levels trading off speed and memory for higher compression rates. ZLIB accepts the range [1, 9] and ZSTD accepts [1, 15]. Default is 3 each

* ''''',noatime'''''

Under read intensive work-loads, specifying noatime significantly improves performance because no new access time information needs to be written. Without this option, the default is ''relatime''. (This may be combined with ''''',lazytime''''')
