You could do RAID 10, which would only lose 4 drives, and have better
read & write performance (no parity calculations). You could use RAID1
on the Areca and add the volumes into a zpool for best performance at
the cost of ZFS's error recovery, or RAID0 on the Areca and mirroring
in ZFS, at the cost of higher resilvering times.

On second thought, a zpool made out of 4 zfs mirrors would be the best
of both worlds, but then you lose the hot swap advantages of using the
Areca.

If the Areca cards have a BBU or NVRAM they should give you good
performance in any mode.
