Which unit of measure is typically used to describe disk capacity?

The unit of measure most commonly used to describe disk capacity is the gigabyte (GB). This is because gigabytes offer a practical balance between size and the scale of data storage. With modern storage devices such as hard drives and solid-state drives frequently featuring capacities ranging from hundreds of gigabytes to several terabytes, gigabytes serve as an intuitive midpoint that allows users to easily grasp the amount of data a drive can hold.

For instance, while a kilobyte (KB) and megabyte (MB) can be used to measure smaller amounts of data, they are less applicable when discussing the capacity of standard consumer storage devices, which typically exceed these smaller units. On the other hand, while terabytes (TB) represent an even larger capacity, they are often used for enterprise-level storage or high-capacity hard drives, which can make the information less accessible to everyday users when considering the storage options they might encounter. Thus, the gigabyte remains the most familiar and practical unit for describing disk capacity in most contexts.
