Many of us have used good old floppy disks in our lifetime. I don’t know about you but I wish my floppy disks had more than 1.44 MB storage space. Dr. Moddnstine has shared a video of a modified floppy disk with 128 GB or more of storage using SD cards.
To be fair, when Floppy Disks were in fashion, most of us didn’t have 100+ GB worth of files to store on them. More information about this project is available here.
