Raid selection advice
I'm currently running two Minisforum N5 Pro's (two separate locations) with replication tasks. I currently have four 24TB drives in Unit1 and two 24TB drives in Unit2. So far, I've setup two vdevs with a striped mirror in the first box, giving two 24TB pools with a mirror for each. The second box has a single drive replicating each of the Unit1 vdevs... giving three drives of replicated data in two locations.
I just acquired two more 24TB drives, and I'm considering getting two more to completely fill the N5's with ten 24TB drives. This is causing me to re-think my current vdev/pool strategy. I love the double redundancy, but I think using three 24TB drives to yield one 24TB pool is a bit low on the capacity usage, especially given these are already in separate boxes/locations. Would it be best to run a Raid Z1 or Z2 across five 24TB drives in a single N5 and then just replicate everything to the other N5? I assume my data transfer rates would also increase if I'm writing to multiple RAID drives vs a single striped mirror. Thoughts?
