Western Digital has announced hard drives that will
have 4K sized sectors instead of 512 bytes.  I'm sure
other manufacturers will do so too...

I wonder about potential effects on performance one
might see re: xfs with a 4k block size and the WD hard
drives with the 4k sectors.  Is this a valid question?

Just a curious (xfs-using) fly on the wall...
