In closing, This guide will get Plex up and running on your FreeNAS without much hassle. I highly recommend this setup as ZFS is far superior to a RAID setup and makes sure that your data stays stable and reliable. Consequently, I find that my Plex server does run considerably faster in this configuration than it ever did when it was on my Windows 10 machine.
