What are the functions of a hard disk

hard disk It is a very important device in computers, because it stores all the information related to the applications we use or the operating system. They are rectangular and protected by a closed metal box. It is the most popular storage method, but do you know what all its functions are?

A hard drive is the most important computer storage mode and depending on its size, it may have a greater or lesser capacity to store information. However, there are still some functions that the hard drive performs on your computer.

It is a storage system


It is a storage system

The main function of a hard disk is to serve data storage device Writing binary data on rotating magnetic disks. These disks are connected to the motherboard, which is responsible for writing and reading information.

Thus, we can access photos, music, videos and those files that have been stored inside, as well as those programs that have been installed on the computer-

Contains the operating system


Contains the operating system

But they are not just concerned with storing information. Hard disks are responsible for containing the computer’s operating system. The place where it is stored is called the boot disk and is the exact place where the computer will go when it is turned on.

In some cases, the operating system is stored on a separate disk because it is not shared with other functions, making booting faster.

Stores centralized information


Stores centralized information

In places where computer networks are used, it is common to use servers that allow the storage of large amounts of data, which is an advantage for large companies.

However, this functionality can also be transferred to small offices or companies that need to keep a backup of their files. centralized hard drives. This way, even if an individual computer loses information, the data will still be stored on this type of hard drive.

It integrates with other electronic devices


It integrates with other electronic devices

One of the last features allowed by hard drives, it is possible to integrate them into other devices, which makes them much more versatile and useful.

For example, we can find hard drives in music devices and even in mobile phones or cars, very useful in the latter, because they allow the user to use navigation systems or save electronic system configurations among other options.


functions of hard drives they expand as technology advances. In fact, their characteristics have improved enormously since they were created and today they support an increasing storage capacity and a faster use. Will they bring new and better functions in the future?

Did you know …

The first hard drive, used in the IBM 350 supercomputer, was the Ramac I in 1956. It weighed a ton and its storage capacity was 5 megabytes in a stack of 50 units.
