Your data is quite out-of-date, considering it's based on an old
version of FreeNAS using ZFSv15, while the latest version of FreeNAS
has ZFSv28.  The TruNAS boxes ship with the newer version of FreeNAS,
so performance will be quite different to what you have listed under
your benchmarks section.  The TruNAS boxes are also appliances, with
hardware optimised to run FreeNAS to get the most out of ZFS.

It all depends on the OP's requirements.  Nowhere in the original mail
was "absolute best performance possible" listed as a requirement.
Just "reliable", "HA failover", and "realtime replication".  All
things that FreeNAS + HAST provide.

Not everyone needs to spend $100K on storage, everytime.
