2. If you have the time, adding XFS + mdraid + dm-integrity [1] (in bitmap mode) as a comparison point against ZFS RAID-Zx might be an interesting data point. That's what I run, personally.
3. Did you give some thoughts to the I/O scheduler choice? Might matter a lot in some cases.
Some remarks:
1. Why does the CoW button remove XFS from the list? Even https://github.com/fenio/modern-fs-benchmark/blob/main/scrip... mentions it has reflink enabled
