Huh, `ZFS`' [draid](
https://openzfs.github.io/openzfs-docs/Basic%20Concepts/dRAID%20Howto.html) might've fixed the main flaw of `raidz` (scary slow IO-intensive resilvers).
Now I *do* wonder however if it requires all `vdev`s to be the same size.
Here's where my memory fails me and this may be completely wrong...
It *may* be possible to make use of smaller drives by striping a bunch of smaller ones together to create intermediary `vdev`s I can then use as part of a `draid` `vdev`, correct?
This is still considerably more awkward (manual handling) than the automatic 1GB chunking `btrfs` & `bcachefs` (RIP), but needs must I suppose.
(Was ZoL capable of this at all? I don't remember. At the time moving off `Linux` wasn't a consideration but now...)
