I have to setup up 25TB of useable storage (not raw) in a FreeNAS machine. Still no disks were purchased so still some flexibility left. What would be a smart way?
a) 4x 10TB HDDs, one ZFS Pool with one vdev and raidZ1. pros: just 4 disks cons: expensive (cost per GB storage isn't the best with 10TB drives), just one disk can fail
b) 6x 6TB HDDs, one ZFS Pool with one vdev and raidZ2. pros: cheaper (better cost per GB ratio), 2 disks can fail cons: 6 disks, not quiet 25TB space useable
c) ?
Of course there always has to be compromise between performce (one or more vdevs), cost ($ per GB ratio), redundancy (raidZ1, raidZ2).
Thanks for thoughts and tips! :)
