I currently use a Synology NAS + Expansion unit. Devided over different pools, one with SHR-2 for 8 drived and one with SHR-1 for 5 drives.
Im going to build a seperate server to run all my dockers. I initially planned to keep my media files on the NAS and connect it through SMB with my server. The more I look into Unraid, the more interesting it becomes to move my drives to the server itself.
But besides the fact that im not sure how I would fit 13 drives into a pc case, I'm also not sure how safe Unraid is. I've read that there is 1 (or 2) parity drives, but does this mean that these drives always spin up with everything you do? Wouldn't that shorten its lifespan significantly compared to a SHR configuration?
With Synology I can setup a scheduled checksum that checks all my drives and even repairs data (bitrot for example). Is this something Unraid can do too?
How are you going to fit 20 drives in that case?
