If the device physical sectorsize is that big, should we perhaps use
that as a hint to align writes to that blocks aligned with that
physical sectorsize?  Right now we use the optimal I/O size, but if
the optimal I/O size is not specified and the physical sectorsize is,
say, 16k or 32k, maybe we should use to calculate for
s_raid_stripe_width?
