I'm working on a new build right now. I already have motherboardboard/CPU/RAM and am reusing my existing chassis.
This is a 4 bay hot-swap case. I also can add two SSDs inside, but I'm really writing more about how to use the main storage bays.
I'm currently behind the times a bit (points at sig), and have not had to deal with ZFS at all.
My original plan was to do 4 x 4TB drive in a RaidZ1. But I've been hearing how the size of drives today makes using parity for an array a "dead end". The size of modern drives makes resilvering from a drive loss too taxing on the remaining disks. At the same time, I'm a bit annoyed at having to replace everything at once if I want to increase storage capacity.
Should I instead be dropping the "4x4" plan and look into doing two mirrored pairs, with the understanding I'll just be losing a flat half of total drive space for the mirroring? Should I even do four drives then? Would it be better to put my budget towards just two drives of higher capacity and then add two more later? From my understanding I can make a pool of just one vdev of two physcials drives, and then expand the pool with a second vdev later.
