Let me preface this by saying I don't know much about raid, nas, servers, or networking.
So I am wanting to get rid of my cluster of external drives, which are currently plugged into my desktop, and switch to a dedicated NAS/server.
I want to gain redundancy, incase a drive fails, and be able to access it through WLAN, while still being able to direct play uncompressed 4k through Plex. I currently have more than 20tb of files and I'm looking to upgrade to around 50tb.
Would a simple raid through motherboard/raid card/windows work? Or do I need to use some software like unraid or freenas?
