Flexibility indeed. This bites me in the butt now. But performance is
sufficient for me, because everything can saturate gigabit ethernet and
there are no VMs involved.

A scrub currently takes 10½ hours. Considering each drive is filled with
6 TB * 80 % = 4.8 TB, that’s an average of 130 MB/s/device which seems not
so bad for 5400 rpm drives.

When I installed drives #3 and 4, I thought long and hard about whether to
use Raid-10 or Z2. The increased resilience won the argument (any 2 drives
over 2 particular drives).

Yeah… I know that for some people, carrying around TBs of movies and TV
series is overkill, but I like having them, and I like having them all in
this neat little box:
