Why Do We Need To Defrag Hard Drive?

Well, the short answer to this question is “Defragging your hard drive frequently can speed up your computer and prolong its lifespan too”. In layman’s terms, you can understand that performing defragmentation is like cleaning the house of your Servers, or PCs. During the defrag process, all of the pieces of data that are spread across your hard drive are put together in a neat & clean, and proper format.

For most computer users, performing defragmentation once a month can be fruitful. But, if you are someone who uses the system approximately eight hours a day for work, it is recommended to defrag your hard drive twice a month. Additionally, if you are tired of slow and sluggish computer performance, you can consider defragmenting. You will certainly experience a noticeable speed boost in one go.

Fortunately, you can defrag your hard drive both manually and automatically using Disk Defragmenter (the built-in Windows feature) and Best Disk Defragmentation Software, respectively. Keep reading to find the Best Disk Defragmenter Programs with their features, pros/cons, and pricing models. All these tools are thoroughly tested and reviewed and hence safe to use on your Windows PC/Laptop.

Factors You Should Consider While Choosing The Best Disk Defragmentation Software

Here’re some of the most important tips and tricks to follow before investing in the Best Defrag Software to use.

1. Ease of use

Performing defragmentation manually can be a cumbersome process for some users. Hence, choosing the best defrag software that can help you automate the entire process, within an easy-to-navigate interface is an important factor.

2. Multi-compatibility

Not every disk defragmentation software is designed to run properly on all the operating system versions. So, before you invest in any program, check its compatibility list, and consider purchasing it if it works on your OS.

3. Scheduler

Choose a reliable disk defragmentation software that provides the Scheduler utility and helps you automatically run the defragging process on a daily, weekly, or monthly basis. Hence, you don’t need to take care of running the defragmentation process on your own, as the software will perform the task on your behalf.

4. Ability To Run In The Background

Always choose the programs that work and run silently in the background. This will ensure that you can work in peace without getting impacted by the tool. Consider investing in the defrag software that can also run automatically while the PC is being booted.

5. Pricing Matters

Although, there are a couple of free disk defragmentation software available in the market that can help you optimize your storage space and speed up performance. But if you can invest a few bucks for the premium version to get advantages in terms of more features, efficiency, speed and more, then you can consider using tools like Disk Speedup, Smart Defrag, etc.
