Good point. As they seem related, would it make sense to combine both the type and rotational flag in one column then?

Punch card readers would be non-rotational and are/were slower than HDDs. And, NVME is a controller/interface technology; the underlying medium is still solid-state.
I can understand that "rotational" might make sense for kernel developers regarding physical data seeking and queuing policies (https://github.com/torvalds/linux/commit/1308835ffffe6d61ad1f48c5c381c9cc47f683ec), but I always found it weird/misguiding to expose it from a user perspective. The property has_shell
of Animal
is good hint for their slowness metric, but Slugs
or Sloths
are have_shell = false
and yet slow (perhaps it is the "Sl-" thing).
I'd be in favor of HDD/SDD over rotation/non-rotational for indicating IO/latency performance.
