Ok, Areca ARC1261ML. Note that results were similar for an 8 drive RAID6
vs 8 drive RAID10, but I don't have those bonnie results any longer.

OK, impressive RAID-6 performance (not so impressive RAID-10 performance,
but that could be a filesystem issue). Note to self; try an Areca
controller in next storage server.
I believe these were both on ext3. I thought I had some XFS results available
for comparison, but I couldn't find them.
