@sjw The thing I want to know the most is this:

"Is there a clear proven advantage over ZFS, or does it come down to a subjective choice over minor pros/cons?"

@UncleIroh ZFS is the clear winner. Btrfs still can't do RAID 5/6 reliably.

ZFS is proven and is production ready. It has so many nice features too!

The only thing I like about Btrfs is I slightly like how snapshots work a little bit more but that's about it. It doesn't perform nearly as well and you can't tune datasets the way you can on ZFS.

ZFS is way more flexible and won't eat your data.

Btrfs had a bug in the kernel just a few years ago that'd completely corrupt your filesystem. Btrfs isn't production ready yet. It also doesn't have nearly the feature set of ZFS.

@sjw Awesome. Aprreciate the reply, especially as I'm about to build a storage array and am looking at comparisons.
