Difference Between 5Mb and 2Gb

This unit would be used to store information, not unlike your memory stick, thumb drive, or camera memory card. The hard drive pictured above weighed over 1 ton, and was capable of storing only 5 Mb or data.


Now some 50 years later, for comparison, it would take over 1,000 of these units to store the information held in a modern thumb drive.
