I agree that RAID-DP is much more scalable for reads than RAIDZx, and

The raw cost/GB for ZFS is much lower, so even a 3-way mirror could be
used instead of netapp. But this certainly reduces the cost advantage
significantly.
Has anyone compared RAID-Z2 against something like LSI MegaRAID RAID-6?
If a sub-$1,000 RAID controller can save thousands of dollars worth of
disks it would somewhat put the lie to the idea that ZFS kills hardware
RAID.
