Trying to figure if freenas z2 10x8TB is safe enough or maybe go z3 12x8TB? I've got 10 drives but to maximize the array I can pick-up a few more drives while they are on sale.
There is a lot of information out there and I'm still confused. I'm hoping this is an easy answer for someone. Yes I know raid is not a back up - before someone says it.
I've messing around with the raid reliability calculator.

I've found information like this.
Start a single-parity RAIDZ (raidz) configuration at 3 disks (2+1)
Start a double-parity RAIDZ (raidz2) configuration at 6 disks (4+2)
Start a triple-parity RAIDZ (raidz3) configuration at 9 disks (6+3)
The recommended number of disks per group is between 3 and 9. If you have more disks, use multiple groups.
