What unit of measurement is used for the capacity of a magnetic hard drive?
The capacity of a magnetic hard drive, or any storage device, is typically measured in bytes. Common prefixes used to represent larger capacities include kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and so on. Storage capacity is an important specification for hard drives and other storage media, and it indicates how much data can be stored on the device. Options B, C, and D represent units of measurement for other quantities (frequency, power, and electric current) and are not used to measure storage capacity.
