ZFS Does ZFS provide data integrity benefits out-the-box default?

I'm reading the handbook now :p but does ZFS offer data integrity benefits with default configs like the installer Auto (ZFS) option on a single drive, or a blank HDD post-install with something like zpool create NAS /dev/ada1?
 
With no data redundancy (single drive; copies=1) there is always error detection, but you can only have error correction if there's data redundancy (mirror, RAID-Z, copies=2 or more).

You can have data redundancy on a single drive by setting copies=2 (or even higher). But this does mean every block is written twice, thus you're using twice as much storage space. Safety does come at a cost.
