Disk Defragmentation Explained

Updated: Nov 30, 2023

Fragmentation occurs gradually as users change, save, or delete files.

The saved modifications for a file are usually stored at a hard drive location that is different from that of the original file.

Supplementary modifications are stored to even more locations. Gradually, both the file and the hard drive become fragmented, and the computer becomes very slow as it needs to search in various places to open a file.

Windows-based computers require periodic defragmentation; Unix and Linux-based computers do not because of a different design for storing data, even if the same hardware is used.

Microsoft Windows provides a proprietary defragmenting tool within its OS. Third-party versions also are available.

Back-end processes such as reading and writing storage media are always invisible to users, who are unable to continuously defragment storage devices because of the impact this has on a system’s rhythm.

Techniques to reduce defragmentation include partitioning and optimization, which allow users to create logical OS hard drives. Programs such as Internet Explorer and databases should be partitioned separately to reduce potential storage media fragmentation.

Why is disk defragmentation useful?

Defragging is a simple process when file fragments are put together to speed up file access. File fragments are put together and quality defragmentation utilities also assemble the free space into a single block to prevent future fragmentation. That’s why you should defragment your hard drive on a regular basis.

What does defragmenting a disk do?

Defragging rearranges the layout of files on your hard disk for faster access. Specifically when (or even if) you need to do it at all is evolving. “Defragging” is short for “de-fragmenting” and it’s a process run on most hard drives to help make accessing the files on that disk faster.

Will defragmenting speed up computer?

This would cause your computer to run slow down since it takes longer to read a fragmented file compared to a contiguous one. To speed up Computer’s Performance, you should defrag your hard drive all the time. Defragging is a process that reduces the amount of fragmentation in file systems.

Should I defrag a SSD?

So, no, you should not defrag an SSD. And performing one will actually reduce the life of your drive. … The TRIM command is supported by the latest SSDs and will optimize the hard drive so that it reduces the number of writes/deletions and therefore extends the life of your SSD significantly.
