Except for NVMe none of the storage standards actually guarantees
sector atomicy, although the whole storage stack traditionally relies on
it..
Maybe we should claim a 4k physical block size for NVMe devices that
hab 512 byte LBAs and a "Atomic Write Unit Power Fail" setting of at
least 8 so that the mkfs sector size logic triggers..
