> Stripe size is 64K, btw.
much too big , best size for a stripset ist same as DB Page Size

Strip Set 64Kb means that the controller will read and write Blocks of 64KB each I/O operation
with a page size of 4 KB 60 KB are moved around with no use , wasting more then 90 percent of the disk read/write bandwidth
(disk caches will reduce the impact somewhat)

my LSI Controller allows me a stripeset as small as 16kb , so it set my page size to match
