ED media is a different chemical composition. In addition to coercivity
differences (600 for "DSDD", about 730 for "DSHD"), ED apparently
does
vertical recording on Barrium-Ferrite? media, with a 1000K bits per second
data transfer rate, resulting in 2.8M (called "2.88M" by IBM, called
"4M"
by Next (unformatted capacity))
My experience with PS/2 "2.88", and MicroSolutions "Backpack 2.88"
were
somewhat lower reliability than conventional 1.4M storage.
