In the late 70’s, the capacity of the typical 5.25-inch floppy disk was a mere 110 KB. These disks were common for the early word processing machines and early CP/M computers.
To equal 1 Gigabyte, you would need 9,532 110 KB floppy disks. As you can see, this is quite an impressive stack next to our 6-foot tall perspective man.
(Keep in mind that rather than including fractions of a disk, I am rounding off to the ones place when counting the number of disks.)
