Capacity may refer to any of the following:

1. When referring to a drive, capacity or storage capacity is the maximum amount of data a device such as a hard drive can hold. For example, if you have a 200 GB hard drive, it has a total capacity of 200 GB, but if you had 150 GB of installed programs it has 50 GB of free space. When a device reaches its capacity, it cannot hold any more information.

In the example below, you can see the Local Disk (C:) has 57.2 GB of 119 GB available and that the Drobo has 1.44 TB of 1.99 TB free.
