ok cool.

I think it has already been said that in many peoples experience, when a disk 
fails, it completely fails. Especially on laptops. Of course ditto blocks 
wouldn't help you in this situation either!

I still think that silent data corruption is a valid concern, one that ditto 
blocks would solve. Also, I am not thrilled about losing that much space for 
duplication of unneccessary data (caused by partitioning a disk in two).

I also echo Darren's comments on zfs performing better when it has the whole 
disk.

Hopefully we can agree that you lose nothing by adding this feature, even if 
you personally don't see a need for it.
