The Extended Density (ED) 3.5-inch Microfloppy was an advance on the HD version, with improved oxide coatings that offered 2.88 MB of storage.

Introduced in 1991 on the NeXTcube, NeXTstation and IBM PS/2 model 57, it was too small an advance in capacity over the HD disk and never became widely used.

The ED disk had an identification notch on the right-hand side that was slightly higher than the one on the HD disk.
