Raid 5 is a great balance of capacity and useful storage with 3 drives. You get 1 drive worth of fault tolerance and 2 drives worth of capacity. I personally have mismatched drives so I run raid 1 in between the matching sizes, and jbod between the raid 1 mirrors (well the zfs equivilent) And my really important data is backed up onto two more drives in raid 10.
Double check that symbol there.

The person I replied to said
as a criticism of using a single 32TB drive.
I argue that a single 32TB drive is less risk than using 2 16TB drives. Am I wrong?
Christ alive.
No. Actually. The 32TB drive is a single point of failure for all your data.
Splitting it means you have 2 points of failure but for only half your data.
From an integrity and availability standpoint the two disk solution, while wildly ridiculous and dumb as fuck, is actually better.
Both solutions are ridiculous and dumb and are not sufficient backup.
