content: If you don't have ECC RAM, don't use ZFS. If your RAM has any defect, it will destroy your data. (oh, and there are no recovery tools for ZFS. It I a enterprise fs and enterprise users have backups) If you don't have 1GB RAM per 1TB disk for ZFS alone to use, don't use it. It will be slow. So as a average home user: don't use it.
