Thanks for your note.  Turns out I have more than one Dell system  
with aac controllers in them :-)

One happens to be a PE 1750 with the PERC 3/Di in it running RAID1.   
It is lightly loaded but is sufficient for that server's needs, but  
is running FreeBSD 4.11 on it.

Is there a way to backport this diskinfo utility to 4.x or 5.x?   
Looks most useful!  On my 6.0 box with a PERC 3/Si card (aac driver  
too) it is showing seek times slower than yours but transfer rates  
faster.
