RAID is not a backup.
RAID is uptime.
It just means you can lose a drive, and keep running "business as usual" until you can replace it. In this case, you can lose two drives before you're at risk of data loss with a third drive loss. It's very, very expensive overhead to ensure you don't have any disruption. In a business environment, that's almost 100% necessary. Personally? You'd probably be fine with RAID parity of 1x drive --- and have extra volume space available.
But RAID is not a backup. You absolutely need to keep backups of the NAS data elsewhere.

However, someone with more knowledge of this might be better equipped to share.
This. AMD doesn't have an Intel Quicksync equivalent so it's not as good for hardware acceleration and transcoding as an Intel counterpart.
The CPU doesn't have native h.264/h.265 decoding so if you have to transcode it going to grind the CPU.
If every device you will be watching Plex with has native support for these then it should be fine on a local network.
Personally, I would use this for storage and offload Plex hosting to another device that can handle transcoding.
I currently use an older ds916 for plex and it works flawlessly and that's because I use an Apple TV with the infuse app. In this scenario the Apple TV does all the transcoding. It's wonderful. Infuse has a plex plugin so you can use the plex app on the NAS to manage your library. I can't stress enough how much this setup kicks ass.

So, what would be good setup for a 4-bay one? I need to keep some photos, which are important and I'd like to make sure those are safe (maybe I need to upload those somewhere else for backup, like "glacier"), but those are like 1-2Tb max. The rest I'd be ok to loose (but ideally not).
