Thanks. So there shouldn't be any negative impact either if sectz is set to 4 KB? In one particular case I experience some perceived slowness on 2 TB WD drive (and I created XFS partition on that drive using sectz as 4 KB). I didn't test however how it compares to default settings on the same drive which would set it to 512 B.
