Nope, NeXT had magneto-optical 128 MB drives, somewhat related. They were 3.5" but using an entirely different media, and were absolutely incompatible with ordinary floppies.
NeXT cubes used a 256 Mb optial drive, and some slabs has. 128Mb optical, and someone said that the turbo color slab had a 230Mb optical drive. Mine did not.
