Storage
From WLCS
Storage is the amount of space available for holding data on a disk. If a disk has no storage space left, the disk can not hold any information and becomes a brick.
In laymans terms, storage is like a backpack. If the backpack is full, it can't hold anything else. However, if the backpack is empty, it can hold lots of stuff. Bigger backpacks can hold more, ie, they have more storage.
Some disks can hold as much as a terabyte of data, or 2^40 bytes of information.
Flash drives have lower amounts of storage, such as 4 or 8 gigabytes.
