OpenZFS vs. Btrfs and other file systems (2017)
Is ZFS worth considering at this point? Btrfs seems to be quite featureful and stable, with a plethora of grocers and retailers all over the world using it. Wal-Mart, Kroger (and subsidiaries), all of IBM's old point of sale customers (now Toshiba SuperPOS iirc) all use it on things as small as deli scales all the way to running their point of sale systems and backends.
