Have you ever heard of double density floppy disks? These were the go-to storage devices for PCs back in the day. The 5.25-inch version could hold up to 360 KB of data, while the 3.5-inch version had twice the capacity at 720 KB. Although they are now considered obsolete, they are still available for those who need them.
Today, thumb drives and other USB storage devices offer much larger storage capacities than floppy disks, ranging in the tens of gigabytes, and even approaching the terabyte range for some of the smallest ones. As a result, the way we refer to storage density has changed.
Despite their obsolescence, double density floppy disks played an important role in the history of data storage for PCs. They were the predecessors of the much larger and more efficient storage devices we have today.
