What is the real reason for the Macintosh SE's upper (second) disk drive for
being so slow (I've measured it to being up to 50% slower, or 1.5 times
longer than the lower drive).  The reason I got from Apple was that it is
"inherint to the system".  

It seems ridiculous to pay more for a machine (Mac+) and get a drive
with degraded performance.  This is found to be true for all of the
Mac SE's that I've tried.  There should at least be some kind of mention
of this when buying an SE, so the the hard disk option can be more
heavily waited as an option.

First, is there going to eventually be a fix to this problem (new 
disk controller chip or something), and why is this issue being kept
such a secret.   I've heard that the actual problem is that the contoller
keeps turn the drive motor off  --  is this true.

NOTE: The disk drive hooked to the external port on an SE runs just fine.
The problem is in the floppy port.  I'd just assume to take out my upper
internal drive and connect it to the external port.
