How a disk writes data.

In Computer,  storage is the place where data is held in an electromagnetic or optical form for access by a computer processor. There are two general usages.

• Storage is frequently used to mean the devices and data connected to the computer through input/output operations - that is, hard disk and tape systems and other forms of storage that don't include computer memory and other in-computer storage. For the enterprise, the options for this kind of storage are of much greater variety and expense than that related to memory.
• In a more formal usage, storage has been divided into: 

1. Primary storage, which holds data in memory (sometimes called random access memory or RAM) and other "built-in" devices such as the processor's L1 cache.
2. Secondary storage, which holds data on hard disks, tapes, and other devices requiring input/output operations.
