@sjw @EdBoatConnoisseur zfs is certainly more established in that regard but there are other options. dm-integrity but I guess that's newish. facebook is one of the companies running lots of btrfs in production

right now the real difference appears to be the stuff with large raid arrays plus all the fine tuning you can do. you can set all sorts of stuff per-dataset meanwhile the btrfs devs say they might get around to supporting stuff like per-subvolume compression options at some point in the future :02_laugh:
