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). > > If you really need the additional space, consider adding second jbod > > with another disks. > > That'd be my approach - migrate a load of stuff off onto another disk > elsewhere, but that's not what the OP wants to do. 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: https://www.inter-tech.de/products/ipc/storage-cases/sc-4100 :) -- Grüße | Greetings | Qapla’ Please do not share anything from, with or about me on any social network. “If I could explain it to the average person, I wouldn't have been worth the Nobel Prize.” – Richard Feynman
