Hello, As You will already have 5 copies (one per server), adding rendundancy on storage is wasty.
I would do a 2 node distributed + replication: 2 servers * 4 disk = 8TB replicated to 2 others servers with same setup. The last server can be abitrer for split brain maybe, or you have to get another server to get 3 and 3. Yes in this setup it's a raid 0, so if you loose a disk, the whole 2 replicated server are down. But you will get much better performance and much more usable space, and still survive a single server crash.
