Maybe older SATA based flash? But I haven't seen any of those in years.
Or, god forbid, rotational storage?

Various NVMe devices do have different limits for things like max
transfer size etc, so if it's related to that, then it is possible that
nvme was used but just didn't trigger on that test case. Out of
curiosity, on your box where it broken, what does:

grep . /sys/block/nvme0n1/queue/*

say?
