What Is an External Hard Drive and Why Do I Need One?

So much of our daily lives revolve around the computer. We use computers to save images and movies, accomplish business, and interact with pals through the internet. Without the hard disc, none of this would be possible. The hard drive is the component that houses all of your computer’s data, from files to the software. It serves as the central storage bank for our digital existence.

Unfortunately, hard discs do not have infinite storage capacity. While 500GB of storage is more than enough for most people, if you have a lot of huge files, such as movies, PC games, and editing files, you may run out of free space. Fortunately, you can always store your computer files on an external hard drive.

External Hard Drive: 

An external hard drive, also known as a portable hard drive, is a device that connects to the outside of a computer through a USB connection and is frequently used to back up PCs or as a portable storage option.

Top uses of External drive:


External drive serves many benefits to an individual. Due to these benefits, one should go for using an external drive. 

Here are the benefits of an external drive.

  • Data Storage
  • Backups
  • Digital editing
  • Data exchange
  • Gaming


External hard discs are used for storage.

Every computer has an inbuilt hard drive. All of your computer’s permanent data is stored on the hard drive. When you save a file, photo, or program to your computer, it is saved on your hard drive.

The storage capabilities of most hard discs range from 250GB to 1TB. That’s more than enough for the average PC user, but if you’ve had your computer for a while or use it as a workstation, you’ll probably need more hard drive space than 500GB. When your hard drive’s capacity is consumed, you won’t be able to store any more data on it, including images, software, and word processing documents.

For this reason, most individuals utilize an external hard drive. Unlike an internal drive, which is permanently installed within your computer, an external hard drive is a device that plugs into a computer port. An external hard drive provides you with more storage capacity for your files.

When you save data on an external hard drive, you can only access it when the hard drive is inserted into your computer. You can use an external hard drive to store files. These files might include:

  • Photos or videos
  • Documents and archival data
  • Projects/portfolios 

When you save older documents on an external hard drive, you’ll be able to preserve more free space on your hard drive, allowing you to keep adding new files while keeping your computer working as fast as possible.


Backing up your hard drive is one of the most critical things to secure your computer data. A backup is just a duplicate of your hard disc that you keep on hand if something happens to your computer.

Moisture and computer viruses may cause catastrophic harm to your computer, erasing its hard drive. If your computer is taken, you may lose all of your data. That is why it is critical to have a backup on an external hard drive. When you obtain a new computer, you’ll be able to transfer the data from your backup to your new hard drive, and you’ll be good as new.

The most modern external hard drives include an automated backup option that will generate backups of your computer once or numerous times each day. However, you may create copies of any file or folder and manual backups of your computer hard disc anytime. 


An external hard drive is a must-have for digital editing. 

Digital Editing includes: 

  • Editing video
  • Editing photographs
  • Illustration in digital format
  • 3D graphics
  • Editing of audio
  • Extensive simulations

Because they need large computations and data processing, they are some of the most demanding jobs that your computer can perform. While your CPU and GPU handle most of the work, an external hard drive is essential.

Data exchange: 

An external hard drive is an excellent method for transferring large amounts of data. The most common data-sharing ways are flash drives, email, or cloud storage. Unfortunately, these methods are inadequate for sending/receiving more than a few files. If you need to transmit numerous terabytes of data, these techniques will be sluggish and cumbersome. Cloud storage can accommodate more data, but upload and download times might be lengthy.

In contrast, an external hard drive allows you to transmit more data quickly. If you need to move data from an old computer to a new computer, or if you need to trade data with a business partner or customer, an external hard drive will be more convenient. Place the data on the external drive and connect it to the computer you wish to transfer. It’s similar to a flash drive but with far larger storage space.


Modern PC games are vast in scope and graphical richness, so they take more space on your hard disc. If you’re a die-hard PC player and your hard drive is becoming overburdened with games, consider purchasing an external hard drive to store them on. Remember that if you don’t have enough free space on your computer, it won’t operate as swiftly. An external hard drive has the potential to improve your gaming performance.

If you intend to utilize an external hard drive for gaming, be sure it has a Thunderbolt or USB-C port. USB Type-A is too sluggish and won’t be able to swiftly transmit data from your hard drive to your computer, resulting in significant latency. On the other hand, thunderbolt and USB-C are high-speed connections that will help you get the most out of your external drive when gaming.

One should use external hard drives because of these elite benefits and ease provided by it.
