It appears to be the conclusion of Wojciech Puchar that ZFS is slow, and 
breaks beyond recovery.  The rest of us don't appear to have issues.

I will agree that ZFS could use a good worst-case scenario 'fsck' like 
tool.  However, between at home and at work (where it's used on Solaris), 
the only time I've ever been in a situation where it would be needed was 
when I was playing with the disks in several low-level tools; the situation 
was entirely self-inflicted, and would have caused major trouble for any 
file system.  (If I'd been storing data on it, I would have needed to go to 
backups.  Again, this would have been the case for any file system.)

ZFS can be a complicated beast: It's not the best choice for a single, 
small, disk.  It may take tuning to work to it's full potential, and it's 
fairly resource-intensive.  However, for large storage sets there is no 
other file system out there at the moment that's as flexible, or as useful, 
in my opinion.
