I understand JBOD works and this is hardware RAID. But can you run 2 RAID 1 (mirror) arrays in this?

    If I'm reading this correctly I think you're asking if it will support RAID 10 (that being 2 drives striped, the other 2 drives striped with the 2nd striped pair as a mirror of the first pair). Yes, this is support and gives good speed & redundancy, but lower total storage (i.e. with 4x4TB drives you end up with 8TB storage and the other 8TB is a mirror).

    Or, perhaps you mean simply 2 mirrored sets (no striping), so in the 4x4TB example you'd have one 4TB drive with a mirror and a second 4TB drive with a mirror (total 2x4TB volumes, both mirrored). Yes, this is also supported with this unit.
