A bit of insight on the floppy drives...
There were five different non-Powerbook external 3.5" drives produced by Apple during the 1980s and 1990s that plugged into the floppy drive port. Make sure you look at the drives carefully when purchasing them to make sure you get the right one. (Both of the ones in the auction linked to this thread would work).
The 400K drive has a raised Apple logo much like the pre-ADB keyboards and mice that shipped with Macs. It does not have a colored logo and has the same indentation on the right side of the floppy slot as the 128K/512K/Plus drive. All are beige.
The Apple 3.5" drive was usually bundled with the IIGS but should work on anything. Mac128K's comments apply to this drive. It's recognizable by its red access light and eject button with a paper clip hole in the middle of it. These drives are platinum and were originally designed to match the IIGS.
The Macintosh 800K drive was sold with the Plus and later. It does not work on Apple II computers and lacks both the eject button and indicator light. These were most commonly bundled with Pluses and are all beige to my knowledge. Apple seemed to drop this drive in favor of the Apple 3.5" drive at some point in the late 1980s, perhaps because this drive was so similar to the 3.5" drive and because the 3.5" drive was platinum instead of beige (Apple went to all-platinum computers in 1987). This drive was introduced before the 3.5" drive.
The UniDisk 3.5" is the same white as the IIc and early ImageWriter IIs. This drive was designed exclusively for Apple IIs. There is a way to pull the onboard Apple II cable to make this drive Mac-compatible. It required a special card to be used with the IIe (if memory serves me correctly it's called the Liron card or something similar; I have the card and drive somewhere and can double-check when I go into the storage closet sometime). These are relatively rare. The drives themselves are 800K drives and will work with the IIe, IIGS, and IIc. They have unique eject buttons that protrude quite a bit from the case and are separate from the paper clip hole. These drives also have red access lights.
The external SuperDrive looks identical to the Apple 3.5" drive but is marked "FDHD" on the front. They should work as 800K drives if plugged into a computer that does not support the SuperDrive. These are also uncommon (this is the only one of these five drive types I have never encountered in 20+ years of working with Apples).
