Although Linux file systems don’t need defragmentation as much or as often as their Windows counterparts, there’s still a possibility that fragmentation may occur. It could happen if the hard drive is too small for the file system to leave enough space between the files.
How do I defrag a drive in Linux?
If you actually need to defragment a file system, the simplest way is probably the most reliable: Copy all the files off the partition, erase the files from the partition, then copy the files back onto the partition. The file system will intelligently allocate the files as you copy them back onto the disk.
Does Ubuntu need defragging?
The simple answer is that you don’t need to defrag a Linux box.

What happens if I don’t Defrag?
If you disable defragmentation completely, you are taking a risk that your filesystem metadata could reach maximum fragmentation and get you potentially in trouble. In short, due to this defragmentation, the life of your SSDs increases. The performance of the disk also increases due to the regular defragmentation.

Does defragmentation speed up computer?
Defragmentation puts these pieces back together again. The result is that files are stored in a continuous manner, which makes it faster for the computer to read the disk, increasing the performance of your PC.
Is defragmentation good or bad?
Defragmenting is beneficial for HDDs because it brings files together instead of scattering them so that the device’s read-write head doesn’t have to move around as much when accessing files. … Defragmenting improves load times by reducing how frequently the hard drive has to seek data.
Will defragging improve performance?
Defragmenting your computer helps organize the data in your hard drive and can improve its performance tremendously, especially in terms of speed. If your computer is running slower than usual, it might be due for a defrag.

Defrag does not change the amount of Disk Space. It neither increases or decreases space used or free. Windows Defrag runs every three days and optimises program and system startup loading.
Is defragging a SSD bad?
