@coolboymew @Cocoa they do have a niche use that is great though for retrocomputing.

original macintosh have a 50-pin SCSI port on the back. it's their only user-accessible expansion port. There's a SCSI external ZIP drive. You can boot your Mac off it and instead of an 800kb slow as balls boot disk you can have a relatively very fast 100 or 250 megabyte boot disk. sure it might fail but you can get a big stack of them, and they're more reliable than the floppy at this point.
