Something else I don't understand: 
The disk should be able to read about 5 tracks/second if you look only
at the revolutions.  Yet when doing something like DiskCopy, the
disk takes more than one second/track to read or write.  What's the
slowdown?  Is the blitter and system overhead really four times the read speed?
