I use OMV 4 on a Raspberry Pi 3b+ with 2 USB-Stick for personal data (~80GB) and a 2TB HDD for media (~1TB of music, videos, pictures). I use the in build Plex addon and in the built in docker I am running my smarthome (Home Assistant, Mosquitto, etc).
But now I want to upgrade this "NAS", one reason is, when one of the storage dies, its gone. I do backup of my personal data every 2-XX weeks ( ) and this is to risky for me, now.
What I want?
I don't know so much over NAS-Systems, but what I know for I backup I need a RAID 1 to mirror on storage. I want my Personal Data and my media on one Storage (3-4TB HDD) for RAID 1 backup.
What is the best system for this?
The Raspberry Pi 4 got USB 3.0, so it is smart to put 2x 3-4TB NAS-HDD on this USB-Ports? Or is a mini-ITX build the way to go?
I don't really have a price limit, but it should be not to expensiv
