Internal Hard Drive vs External Hard Drive: Difference and Comparison

Hard drives are the extra storage hardware components that are used to store various data inside them. We can store photos, videos, applications, music, etc on hard drives.

And therefore, hard drives are divided into two variants: the Internal Hard Drive and External Hard Drive. Both of these hard drives have their speciality and functions that are distinct from each other.

Here, we are going to discuss the differences elaborately.

Key Takeaways

1. An internal hard drive is inside a computer or laptop for storage and running programs. In contrast, an external hard drive is connected to a computer via a USB cable and is used for backing up files or expanding storage capacity.
2. An internal hard drive is faster and more reliable than an external hard drive, which may be prone to physical damage or corruption.
3. An internal hard drive requires technical expertise to install and replace, while an external hard drive is easy to connect and disconnect.

An Internal Hard Drive vs An External Hard Drive

The difference between an internal hard drive and an external hard drive is the placement of the respective hardware. Generally, an internal hard drive is situated inside a computer; therefore, we can not see it unless we open the screws of the computer. On the other hand, generally, an external hard drive is situated outside a computer that is connected externally with the help of a cable, and therefore we can see an external hard drive.

An internal hard drive refers to the storage hardware that saves data and can easily be accessed through the data that is saved inside the computer without any problem.

Generally, an internal hard drive is situated inside a computer, and therefore we can not see it unless we open the screws of the computer. An internal hard drive is also commonly termed as the main or primary memory.

On the other hand, an external hard drive refers to the storage hardware that saves the data that is transferred from the internal hard drive to it externally from the computer.

Generally, an external hard drive is situated outside a computer that is connected externally with the help of a cable, and therefore we can see an external hard drive. An external hard drive is also commonly termed secondary memory.

What is an Internal Hard Drive?

In computers, there is hardware where we can store and save our data, such as photos, videos, music, movies, etc.; therefore, that hardware is known as an internal hard drive.

It helps us to store the memories or the works people would like to access whenever required. Hence, it is termed as the main or primary memory.

It is known to be the primary memory because it is the memory we can find inside the computer since an internal hard drive is placed inside it.

An internal hard drive is easy and time-saving to use, as it is initially connected to the computer. We only need to click on the files that we have saved earlier on the desktop. It’s just a click away to find our data. An internal hard drive is not portable.

This is because it was initially attached to the computer when we bought it. We can only take out the hard drive to repair it when it shows some issue.

Otherwise, we need not worry about the internal hard drive. It also has a great storage capacity. It is fast to use and very convenient.

There are both advantages and disadvantages of an internal hard drive. An internal hard drive has several advantages, such as it has great storage capacity, it is easily accessible, they are cheaper, great speed, etc.

On the other hand, the disadvantages are that it is not portable, very big in size, energy efficiency, inevitable failure, etc.

What is an External Hard Drive?

Apart from storing data inside the computer, those data or some extra data that doesn’t fit inside the computer anymore are transferred into hardware that is known as an external hard drive.

This hardware is known as an external hard drive because the data are stored outside the computer. This memory is commonly known as secondary memory, as it is a backup memory storage system.

It is a bit complex and time-consuming to access through an external hard drive as it has to be externally connected to the computer with the help of a cable.

People only tend to buy an external hard drive when there is a shortage of space in the internal hard drive, if they are frequently required to carry data from one place to another, etc.

This memory can be carried to any place as it is portable and very convenient to carry because of its size and structure. But, the major drawback of an external hard drive is its storage capacity, which is very small to carry out larger files or data.

An external hard drive has no severe pros or cons, but the minor pros and cons can sometimes make a major difference. An external hard has several advantages, such as its backup drives, it can be easily portable, it gives extra storage to store data, etc.

And its disadvantages are that it has slow speed, and it easily gets lost or broken, limited storage, etc.
