August 1, 1989: Apple gives the Macintosh SE a storage bump, courtesy of the new SuperDrive. The high-density floppy disks offer an astonishing 1.4MB of storage.
In terms of portable storage, it’s a big step up for most Mac owners. The HD floppy disks compare very favorably to the 400KB Single Side Double Density (SSDD) disks and 800KB Double Side Double Density (DDSD) disks in use at the time.
