I currently have a UnRaid 30TB NAS, but recently I got the Dune players, and the combo is causing pauses in the middle of movies. I had a problem when I moved to M3xico when a HDD or 2 failed somehow from the move. I replaced the HDDs, and then left it until about a year ago. I discovered some movies would pause, and thought it was the parity rebuild. I just got a USB 8TB WD, and copied a few movies that were pausing, and found out there was no problem with the movies. I have been thinking for quite a while about getting another setup to play the movies from, and just use Unraid to backup all of them.
One of my Dune players will accept a HDD to put inside it, and also a SATA external as I recall, plus a USB3 port for more external drives. The other only accepts external USB drives. I contacted Dune, and they said that I can also access the drives from other media players, and gave me the info on how to reach them from another setup. We will see what happens next week when the 3 10TB USB external drives arrive.
The nice thing about the 10TB HDDs is that I can then move the NAS to another room, and only turn it on when I need to add media files to it. I really like the Dune players especially with the latest Kodi, and the AEON MQ8 interface (I use MyMovies for metadata, and the combo is great).
I also have Plex, and JRiver in my setup... I like to have multiple ways to play media in case Murphy shows up.
