So another update from me, because sometimes things go slow. I've booted a #NixOS live image and the #badblocks program is running a check of my four 4TB drives (been running for 86 hrs and done 84% I think the last time I checked).
I did change my decision to use #NILFS2 & #RAID6. After deliberate consideration I've switched my choice to #ZFS with #RAID10.
— no longer NILFS2 because it doesn't have compression and ZFS even includes the kitchen sink
