But that is a single drive. I have an array.

I do not run RasPi OS on any of my RasPis and never have.

AFAIK, RaspBian does not support ZFS, and nor does Debian upstream.

I have used Linux `mdraid` a fair bit and it is somewhat
labour-intensive. I wanted to give ZFS a try and I have been
impressed: it is fast and easy. The tool creates the array, manages
partitioning too, formats it, makes a mountpoint and mounts it for
you, all automatically, in a single step.

I don't personally need snapshots or copy-on-write or any of that, but
just as for an array-management tool it is more convenient than
mdraid.
