ZFS guarantees consistency in a redundant setup, but it looks like
your pool only consists of one drive, meaning zero redundancy
This is not a true statement. Redundancy is not required for
consistency. Consistency is assured by zfs writing transaction groups
in order and commiting the data to disk prior to transitioning to the
next transaction group. If the disk fails to sync its cache and
writes data out of order (data from multiple transaction groups), then
zfs loses consistency.
