Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

In today’s digital and social media world, we need huge storage space to store our data. External devices offer good possibilities for data portability and backup of our computer’s data.

We are all digitally connected and focused on the desktop or laptop. We use computers for communication, sharing photos, videos, editing documents, project activities, professional activities, and more. All this data is stored on the internal or external hard drive of a laptop or desktop computer.

In other words, the hard drive is the component where all the data is stored. Unfortunately, this device is limited in space, and if you frequently use all the applications and software of your computer, sooner or later, you will most likely run out of space. External hard drives are used in such situations.

External hard drives are portable, let you back up data from your computer, and you can take them with you wherever you go with the data loaded.

Benefits of using external hard drives

Whether you use your computer for personal or professional use, you will need an external hard drive for the following reasons:

#1. Data portability

The main purpose of an external device is to store data.

You can even connect smartphones, tablets, and other devices, transfer your data, and store it on external devices. Technically, when your internal hard drive is almost full, your system slows down, and that’s because the processor uses space to store temporary files for reading (this is called cache).

So if the CPU doesn’t find enough space, the reading process will slow down, thereby lowering the performance of your entire computer. In such cases, the user transfers the old data to the external device and makes space on the internal device

#2. Security

One of the benefits of external devices is that they can be used as security devices to store personal information. To protect personal information such as financial data or sensitive information, content may be transferred to an external device, and the device may be stored in a secure place.

Whenever you want to access this data, you can connect your device to your computer and retrieve the information.

#3. Faster Data sharing

No matter how fast your Internet or intranet is, large amounts of data transferred over the network take time. One method of transferring large amounts of data is connecting an external device to a computer, copying the data, and physically transferring the device and retrieving the data.

It also helps avoid network congestion or high bandwidth usage. The latest external drives are equipped with high-speed connections such as USB 3.0, USB 3.2, and Thunderbolt, which significantly boost the transmission speed.

#4. Intensive applications

Modern computer games, high-end applications, high-end computing activities such as video creation and editing, film screenings, advanced simulations, etc., require more graphic detail, and the system takes up a lot of space on your hard drive.

In such a scenario, the external device plays a key role in storing data, files, and other information, which will take up a lot of space on the internal drive.

If you are a dedicated computer gamer and your hard drive is full of games, an external hard drive for storing games will make things easier. External hard drives can improve your gaming performance.

If you’re looking to replace your fast filling drive and aren’t sure which one to buy, this section highlights the differences between a traditional hard drive (HDD) and an SSD:

General difference: Traditional hard drives have mechanical parts such as platters and heads that are used to store and access data. This method is slower, less efficient, and less expensive.

SSDs use memory chips to store and access data. It is the latest technology, and it is faster than the traditional one. Although these devices are expensive, they are more efficient than regular HDDs.

Read/Write Functions: HDD read/write tasks take 30-150 MB per second (MB/s), while the same process takes about 500 MB/s for normal SSDs and 3,000-3500 MB/s for new NVME SSDs.

4K data: 4K data is stored in blocks, HDD speed varies from 0.1 to 1.7 MB / s to access this data, while SSD and NVME-SSD speed from 50-250 MB / s to Use 4K read/write.

Lifespan: The higher the wear on parts, the shorter the drive life. Hard drives have mechanical parts that keep moving while data is recorded. SDDs store data evenly across all cells, and newer SSDs use bad block management, which replaces bad cells with new ones. In general, SSD life is much longer than HDD.

Price: Obviously SSD, comes after HDD at a premium. Even with the higher prices, consumers prefer to use SSDs because of the increased performance, high integrity, and data security.

We hope these factors will help you choose the right system for your system.

Conclusion 👨‍🏫

If you are looking for a device to store your old files and data and don’t want to spend a lot of money, you might prefer to buy an HDD. You get a great selection at an affordable price.

On the other hand, if you need to speed up system startup and want all your applications, programs, and data to be available faster, you can opt for an SSD. SSD significantly improves overall speed and performance.

If you are looking for more storage space and better performance, it will cost more, while hard drives, an older technology, are usually cheaper than SSDs but slower in terms of efficiency and performance.

Regardless of whether you are using an SSD or HDD, you should keep your device clean. Your operating system requires a lot of storage space to function, and a small amount of storage space can slow down your computer and even crash it.
