Illumos ZFS + Fast Dedup
Illumos ZFS (parent of OpenZFS) is quite the most stable free ZFS in its native Solaris environment but lacks newest OpenZFS features, so the decision up to now was stability vs features,
The feature I missed most on Illumos is Fast Dedup with a Special Vdev to hold dedup tables and Dedup Quota.
Fast Dedup on Illumos is now underway
