Defragmenting SSD or HDD in Windows: Is It Necessary?

When you start using a new hard disk, it works at full capacity, something that does not remain over time. And is that this performance may decrease as we store data or install and uninstall programs. One of the methods that have always been used in the past to solve this problem is defragmentation. Currently with SSD disks it is practically no longer used, but is it still recommended?

When we talk about defragmentation , we are referring to the process by which the files are ordered for all of them to be stored continuously, as just as possible, so that they can be accessed as quickly as possible, thus achieving improve system performance and speed.

Defragmenting SSD or HDD in Windows

Today hard drive defragmentation is no longer as important as it was in the past. For example, in the times of Windows XP, it was a recommended process since it achieved greater performance, especially when using large files, to the computer all the fragments of the disk continuously.

Since Windows 10 was released, this basic maintenance task is performed automatically and continuously by Microsoft‘s own operating system. Even so, the option to force explicit defragmentation of a disk drive is still available on the system, so there are cases that may be recommended for certain situations. We can access it by typing defragment in the search box of the Start menu.

In the case that we have a mechanical hard disk, we can use it when we have the disk partitioned , so that we have the system unit in one and the other with stored data. It may also be advisable to do it when we have external storage units that we use frequently by deleting and adding files since they will tend to fragment more quickly. In addition, in case we use an older operating system such as Windows 7, we should also consider defragmentation as a method to improve the performance of the computer.

With SSD disks we should never defragment

For some years now, SSD disks have become an element that has begun to form part of our computer, taking advantage of their great advantages, since their performance and speed is much higher than that of mechanical hard drives. These discs are specially used to install and run the operating system, applications and games, in order to obtain better performance.

These discs, unlike the mechanical ones, have practically instantaneous access to the data by not having a head that has to move to each part of the file and read it sequentially. Thanks to this, fragmentation is not a problem on SSD disks , so we should not use defragmentation.

SSD disks have a useful life based on the number of writes, so if we perform defragmentation tasks on them, we will only achieve a drastic loss of their useful life. In addition, in the SSD the existing files can be replaced by others automatically and enter any information that we need to save there, so the defragmentation function lacks any sense in them.
