A Fedora desktop spin, which already uses Btrfs by default, plans to also enable transparent data compression using the library Zstd from Facebook by default. This is about the upcoming release of Fedora 34, expected to appear at the end of April. In addition to saving disk space, transparent data compression is also aimed at reducing wear on SSDs and other flash storage devices. Moreover, a performance increase in both read and write operations is anticipated.
The use of transparent compression will affect the operation of certain utilities, such as du, since the file size may substantially differ from the disk space it occupies. As an alternative, utilities like compsize.
