I am setting up a new FreeNAS server and am looking for some guidance. I see a lot of recommendations about using raidz2 or raidz3 depending on the number of disks you have, but 1 thing that is not clear is if "hot spare" drives are counted in that.
My server has 9 x 2TB disks. I will also be backing up to a cloud service which I purchased an "unlimited" plan with.
I was thinking that 8 drives should be in-use with the 9th drive being a hot spare. If that is true, am I better off creating a mirrored (2 x 4 disk) VDev? Or is raidz2 a better option? Should I even be considering raidz3?
It looks like I could also configure 8 or 9 disks in a raidz2, which would give me 12TB or 14TB of storage with a reasonable amount of failure protection. Perhaps that is a better option since a mirrored configuration would only give me 8TB of space?
