Newbie here. I'm planning on purchasing my first NAS in the coming weeks. I'm planning on storing a very modest media collection (~4TB) and our photos, videos, and music (also very modest, maybe 1TB in total).
I'd like to give myself a fair amount of headroom on the storage since I plan to have this for year. I do intend to stream my media to my Apple TV 4k using Infuse, though I may want to try Plex later on.
My plan is to purchase a 923+.
The thing I'm having the most difficult time deciding is storage configuration. I've read enough times that RAID is not backup, so I'd like to backup my RAID array to another disk in the 923+, or to an external HDD (depending on the chosen config).
Here are the options that I'm considering. I'm also open to suggestions. Again, I'm new to all of this.
Option 1
12TB x 3
RAID 1 Mirror = 10.9 TB usable
3rd drive used as a backup of the RAID array
Option 2
12TB x 4
RAID 6 or RAID 10 (I have no idea here) = 21.8 TB usable
No idea what to do for backup here. This pushes my budget. I may purchase the cheapest external HDD I can that could fit 8-10TB since I would never fill up a 21.8 TB drive.
Any advice would be appreciated!
