To paraphrase, "ZFS is the worst filesystem, except for all those other filesystems that have been tried from time to time."

It's far from perfect, but it has no peers.

I spent many years stubbornly using btrfs and lost data multiple times. Never once did the redundancy I had supposedly configured actually do anything to help me. ZFS has identified corruption caused by bad memory and a bad CPU and let me know immediately which files were damaged.
