A single disk pool is a poor practice, but unfortunately widespread when storage arrays are used. ZFS is still beneficial when using a single disk pool though.
  • There is double or triple redundancy in the metadata, that makes the file system resilient to moderate disk corruption.
  • You can also enable ditto blocks (copies) so data itself would recover from some disk blocks issues.
  • ZFS will immediately spot corrupted data or metadata while UFS will return corrupted data without notice and might panic the OS if metadata is corrupted.
  • Finally, telling you have more UFS recovering tools is questionable. With ZFS, you can recover from situations where UFS would be helpless.
