I am sure this is not the first discussion related to this... apologies for the duplication.
What is the recommended way to make use of a Hardware RAID controller/HBA along with ZFS? Does it make sense to do RAID5 on the HW and then RAIDZ on the software? OR just stick to ZFS RAIDZ and connect the drives to the controller, w/o any HW RAID (to benefit from the batteries). What will give the most performance benefit? If there isn't much difference, I just feel like I am spending too much money on a RAID controller but not making 100% use of it. :) .... perhaps, maybe the route I should take is to look for drives (SAS or SSD) with built-in batteries/capacitors - but perhaps then it becomes much more expensive then the HW RAID controller?
