I fear I'll have to correct that a little. This 13.5 figure seems to be 
incorrect, in another try it was also shown at the beginning, but then 
quickly got up to >20. Also, a buddy just told me that this 4k stuff applies 
only to most recent drives, as old as 5 months or so.

When I use parted on the drives, it says (both the old external and my 2 
months old internal):
Sector size (logical/physical): 512B/512B
So no speedup for me then. :-/
