What a wonderful surprise! The nearest thing seem to be modern (v5) XFS + dm-integrity, I'll have to see a comparison once it's stable enough.

A thing ZFS suffers from is fragmentation (no way to defragment in-place nor preallocate so stuff like bittorrent doesn't play well with it), which it justifies with its CoW design, wonder if/how it mitigates the problem.

If we're looking at 'future' filesystems, is fragmentation really an issue in an SSD world? Not that there isn't a lot of spinning rust (and will be for quite a while), I don't think it's unreasonable to assume "most block storage is going to be SSD in the future" when allocating resources to priorities.

Fragmentation in ZFS wastes a lot of space. So it doesnt matter if it's SSD or not.

		You're right...I didn't think that through.

The day I can furnish my NAS in SSDs for roughly the same price as HDDs probably won't come before any current filesystem is obsoleted for some reason or another, methinks.

		Probably true. My bad.
