ZFS is novel and complex.  It requires different thinking than 
traditional partitions/ slices, volumes, filesystems, etc..  I suggest 
that you build a FreeBSD VM, give it an extra disk, and play with ZFS. 
When you think you understand how to create, use, modify, and destroy 
pools, datasets, properties, and snapshots, add another disk, create 
another pool, and play with replication.  Then you will understand 
whether or not ZFS makes sense for your systems and operations/ 
maintenance/ disaster preparedness procedures.
