Performance is all but irrelevant in this case

You say that but when the system starts to lock up you might change your tune

Why would it lock up? ZFS will use as much RAM as you give it and it doesn’t seem CPU-bound unless you turn on encryption. It’s not Ceph. Why do you expect ZFS to lock up and Btrfs not to?

I used it on a Pi 4 in 2019 for an USB-connected mirror and it worked well. Unencrypted throughput was upwards from 200MB/s. Encrypted throughput dropped down to under 100MB/s due to insufficient compute.

It’s a 4gb pi4, think it could boot from ZFS?

You could boot from from an SD and then store data on a external drive. I would go Btrfs over ZFS unless you have at least 3 or more disks

I would try it. My only issue is I have no idea how to set it up on root on a Pi. Perhaps there’s docs somewhere. If had to setup a new Pi with Pi OS/Debian/Ubuntu today I’d definitely try it. Most of my Pis are running OpenWrt though.
