Agreed, mirror vdevs are the way to go. Here's a post that explains the tradeoffs between RAIDZ and mirror vdevs in great detail: http://jrs-s.net/2015/02/06/zf

I'm still not sure what setup I have. I really should have written down every decision I've made while building my NAS (I think I've now found articles that disagree with every single choice I made) $ zpool status pool: BoxODisks state: ONLINE scan: scrub repaired 0 in 9h20m with 0 errors on Sun Jul 31 01:31:31 2016 config: NAME STATE READ WRITE CKSUM BoxODisks ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 gptid/18059e22-b6a4-11e5-9cca-0cc47a6bbf34 ONLINE 0 0 0 gptid/194649b1-b6a4-11e5-9cca-0cc47a6bbf34 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 gptid/1a86b3cc-b6a4-11e5-9cca-0cc47a6bbf34 ONLINE 0 0 0 gptid/1bcd3ad6-b6a4-11e5-9cca-0cc47a6bbf34 ONLINE 0 0 0 cache diskid/DISK-S24ZNWAG903847Lp1 ONLINE 0 0 0 I think I have mirrored vdevs. What does that mean for replacing failed disk/s? What does that mean when I want to upgrade to 8TB drives? The biggest "mistake" I made was buying a very expensive 4 bay enclosure - 4 drives is not enough.

  When you want to upgrade, you can offline and replace each disk, then resilver, in turn. If the pool is set to autoexpand, you'll eventually get a total capacity of 16TB. You can do this for all the disks, or for each mirror separately in two groups of two.
