When you save data to your system or when you install a program on your system, all this information is stored, recorded and written to this device. Generally, data is stored magnetically, so when you turn off your system, the information recorded on your hard drive will remain intact and will not be lost. In other words, a hard drive is an electromechanical device for storing data and digital information.

As mentioned in techtarget, a hard disk or hard disk drive is a type of data storage unit used in computers and electronic devices. This device is capable of permanently storing data, files, and programs. Hard disks are often housed in a protective case as a rotating disk with magnetic plates. Data is stored on the plates using magnetism and can remain there even after the system is turned off. Hard disks can be accessed and managed by the operating system and various software. However, the trend is currently changing towards the use of high-speed SSD memories for data storage.

Using a hard drive to display images

Normally our hard drive is full of zeros and ones. Our processor processes the zeros and ones so that we can finally see the output we want. All these zeros and ones are located inside the system’s hard drive, which is why the processor starts its processing by accessing them. Every image that exists in our system is actually hundreds of thousands of zeros and ones placed next to each other with an extension that is stored on the hard drive. These zeros and ones are stored in the jpg format or any other extension.

Now when we click on it, all the zeros and ones from the system’s hard disk are sent to the processor, and the processor processes them and finally displays that image or video to us. This is the entire process that occurs in your system so that you can view an image or game.

History of the hard drive

Hard drives are one of the oldest methods of data storage, dating back to the 1950s. In 1956, IBM introduced the first commercial hard drive, the IBM 350 Disk File. It was the size of a small bedroom, could hold 5 megabytes of data, and spun at 1,200 rpm. Since then, hard drives have continued to improve in capacity, speed, and performance.

In the following decades, hard drives underwent many changes. Their physical size became much smaller and they achieved higher capacities. Also, new technology such as magnetic technology and nano memory were used in hard drives. Today, hard drives are still used as the main storage solution in systems. However, solid state drives (SSDs) are emerging and are considered a suitable replacement for hard drives in many systems due to their high speed and space and cost savings.

What are the types of hard drives ?

Various aspects of hard disk types can be examined in terms of type of use, external and internal hard disk, SSD and HDD hard disk, communication ports, size and size, etc. Hard disks come in many different sizes and shapes in terms of type of use. For example, old Nokia phones have a hard disk with a capacity of 8 GB. The most common and common size and shape of a hard disk is 2.5 inches or 3.5 inches. Keep in mind that one of the most important points to pay attention to is the classification of hard disks. For example, home category, storing images and videos, storing data in bits and four hours, etc.

Today, hard drives are available in two types, internal and external, in the markets. SSD and HDD are the most important and widely used types that can be used in laptops. SSD is three to four times faster than mechanical hard drives, which is why it will affect the performance of your laptop. You can choose and purchase the model you need according to your type of work and field of activity. In this section, we will introduce you to the types of hard drives and their uses.

Internal hard drive

The internal hard drive, or the internal memory of the system, has the ability to store and protect all your programs, files, and data on your system without having to worry about them being erased or deleted. An internal hard drive is a hard drive that is located inside your system and is connected directly to the motherboard. Replacing and upgrading a hard drive in desktop computers is very easy, all you need to do is disconnect the old hard drive from the motherboard and connect the new hard drive to your system. However, on the contrary, upgrading a hard drive in a laptop is not so easy, and to replace your hard drive, you must first read the manufacturer’s website so that you can replace your system’s hard drive correctly.

Keep in mind that internal hard drives use SAS, SATA, IDE, ATA, and SCSI cables to connect to the motherboard. The price of internal hard drives varies depending on the amount of memory and brand they have. In other words, the more memory and storage space they have, and the more famous the manufacturer, the higher the cost of the hard drive. In terms of storage capacity, this type of hard drive typically ranges from one to eighteen terabytes. Of course, keep in mind that you can increase the number of hard drives in your system depending on your needs for more storage.

External hard drive

An external hard drive is a hard drive that is independent and portable and is located outside your system. If you are interested in keeping your information and data private and permanent, using an external hard drive is essential for you.

External hard drives are available in two types: portable and desktop in markets around the world. The desktop type of external hard drive is mostly used for backing up data and information as well as storing them due to its high weight and large volume. The desktop type of this hard drive also has higher speed and a very high and impressive memory capacity. Portable is another type of external hard drive that can usually be connected to your system via a thunderbolt or USB cable. This type of hard drive is mostly used for storing content and movies that are very high quality and HD because it can store and store information and backup files in the best possible way.

The main difference between an external hard drive and an internal hard drive is that you can easily remove your external hard drive from the system, but internal hard drives are usually located inside the system and cannot be easily removed.

Understanding the internal components of a hard disk

As we know, the design of hard drives is such that their internal components are not visible. In the following, we intend to introduce and examine the internal components of hard drives:

The structure of the hard drive consists of two basic important parts:

1. The mechanical part of the hard drive or hard drive assembly

2. Hard drive electronic board or logic board

A hard drive is made up of internal components, which include:

1. Enclosure or media

2.Plotter or rotating disk

3. Flexible flap

4. Hard Head

5. Hard disk cover

6. Hard drive support arm

7. Voice Coil Motor or VCM

8. Central controller or Actuator

9. Spindle motor

10. Hard Head Slider

Types of hard drives in terms of technology

Nowadays, to speed up our systems, we usually either buy powerful systems or try to upgrade our system components so that they can meet our needs. Considering all of this, we still cannot say for sure which choice is better; because each of them has several advantages and disadvantages. One thing that you should keep in mind before buying the hard drive you need is that the hard drive you choose should be in a good position in terms of technology, performance, security, and storage speed. Hard drives are categorized into two categories: SSD and HDD in terms of their technology and performance, which we will explain to you below.
