Thank you to all who have responded.
Yes I am using some leftover desktop-type hardware for this machine with non-ECC memory. I had thought about upgrading the storage from 2x4TB in RAID1 to 4x4TB or 6x4TB in RAIDZ2 at some point but I was not planning on upgrading any of the other hardware.
I use this just in my home, for a few uses but mainly storing photos and videos. I do not use any plugins or jails. I do use this for PLEX but I run the plex server on my main desktop computer and I have a network drive mapped to the FREENAS machine. I know that sounds goofy but I remember trying to set up the PLEX plugin when I started out and I couldn't figure it out so I gave up. I may try again if I upgrade the FreeNAS version. I have a couple of apps on my families smartphones that automatically upload new pictures/videos taken to folders on the NAS as well. There is no internet access to the NAS.
Thank you for the instructions on how to perform the SMART test on the OS disk, here is that output but it looks like it's good to me:

I uploaded the debug output to this post. I will memtest the ram now since the HDD seems to be okay. Thanks again for the opinions.
