for putting floppy disks in it
hard disks are generally contains within the computer and contain FAR more memory than a floppy disk does. floppy disks generally contain 1.44 mb where as hard drives are constantly developing and are currently about 1TB MAX. floppy disks are external in the same way as CD's
You would need 729 floppy disks to hold 1GB of data. This is because:1 gigabyte is equal to 1,073,741,824 bytes1 floppy disk can hold 1,474,560 bytesSo floppy disks per gigabyte is equal to 1,073,741,824 divided by 1,474,560, which is 728.18 disks. This means you would need 729 disks to hold the full 1GB.
