Lots of advantages? That rather depends on the context in which you are using, or intending to use, it and what you are comparing it to. IMHO, for the context in which it is most potentially advantageous, the correct, or most useful, comparison would be between ZFS and LVM plus some variant of EXT or other filesystems.

You seem to say that there is only one. Of that one, here are two:
You would do yourself some favours by reading, eg, the performance testing and other comments that have been published in various tests over at
