I have an AT with a Toshiba 3.5" 720K drive.  This same drive worked
fine on an XT, but here the performance is noticeably "sluggish". 
Getting a directory takes about 2 sec to get the volume label, 2 sec to
get the directory name, 1 sec to list the files, and 2 sec to list the
bytes free.  The same operation on the XT might take 3-4 secs
altogether.  Copying a file takes about 5 sec, compared to 2 or 3 on an
XT.

I have a techie friend who's said he's seen very similar behavior in all
AT's he's installed 3.5" drives on (perhaps 6 or 7 altogether).  There
are nor retries, data or seek errors, or any trouble with data
integrity.

What gives?
