I disagree, see posting above.

ZFS just accepts it 2 or 3 times. after that, your data are passed away to 
nirvana for no reason.

And it should be legal, to have an external USB drive with a ZFS. with all 
respect, why should a user always care for redundancy, e. g. setup a mirror on 
a single HDD between the slices??

You don't have to have redundancy. But if you don't then I don't know how you can expect the
'repair' features of ZFS to bail you out when somethign bad happens.
This reduces half your available space you have on your drive.
Mirroring between slices does more than that. it' will ruin your performance also. It's be much better to set 'copies=2', though that will still reduce your space by half.
