Awesome, thanks for the post about what solution you went with. I may look to address my personal NAS situation late next year or sometime in 2017, and would be interested on how it goes with FreeNAS.

Sometime before that happens, my personal server for mail is likely to move from CentOS to FreeBSD. I kinda want to remove anything Linux from my personal side for a variety of reasons. As nice as my (pre BTRFS) ReadyNAS units have been, it's time to stop the bitrot and other data corruption going on as I am trying to cart forward decades of digital stuff.
