As Fred says, different animal.  The box of 3M DSED sitting in front 
of me proudly proclaims "Barium Ferrite"  and "Extra High Density".  
The density indicator aperture is located about 5/8" from the top of 
the jacket, as oppsed to about 3/8" for the aperture on a DSHD disk.

Like DSHD, DSED was very expensive when it first came out.  I think I 
paid about the same for my first box of HD diskettes (Fuji and about 
$45) as I did for my ED.  Curiously, this is also about what I paid 
for a box of Dysan 8" floppies.  Must be one of those universal 
constants.  I don't recall pricing for DS2D media when it was new.
