Correct.  However, you do not need the controller to get high
density with the AE drive.  There is a difference, though.  If
you use the AE high density drive with the IIGS drive port
rather than a superdrive card, you will get a 1.6MB GCR
based high density format.  Yes, it is high density.  It lets
you store 0.2MB more than the PC 1.44MB format.  It is not
however PC compatible.  Physically, the disk should be
readable by a Mac, but I do not think the MacOS driver
supports the 1.6MB GCR format.  Lastly, because the AE
high density is the result of its driver, you cannot boot from
a 1.6MB disk.  You must have GS/OS loaded and the AE
driver loaded to access 1.6MB disks.

Not anymore.  The most common SCSI drive that supports
this now is the SCSI version of the LS-120 SuperDisk.
