I would not discount the performance issue...
Depending on your workload, you might find that performance increases
with ZFS on your hardware RAID in JBOD mode.

I
conducted a couple of tests, where I configured my raids as jbods and
mapped each drive out as a seperate LUN and I couldn't notice a
difference in performance in any way.
Not sure if my original points were communicated clearly. Giving JBOD's to
ZFS is not for the sake of performance. The reason for JBOD is reliability.
Because hardware raid cannot detect or correct checksum errors. ZFS can.
So it's better to skip the hardware raid and use JBOD, to enable ZFS access
to each separate side of the redundant data.
