Any honest opinions you wanna throw at a first time NAS user :D?

I'm not using or will be using any kind of RAID/ZFS.
The 3tb drive has tv shows, the 2tb movies and the 320gb photos and documents.

I have my photos and documents backed up on OneDrive and if my 3/2tb drive fails, idc, i'll simply download them again.
This NAS is more of a backup to a backup + media server
