Why You Should Never Defrag Solid State Drive (SSD)?

As we all know, defragging a hard disk drive can greatly improve its performance. But, is it advisable to defrag a solid state drive (SSD)? This article will focus on this issue and tell you why you shouldn’t defrag a solid state drive.

When it comes to disk defragmentation, many users will give a lot of kudos to it in that it is indeed able to greatly speed up the traditional hard drive. It’s because that the hard disk drive is a disk made up of magnetic material with a drive head, which will move around to find data when we try to read/write data on the disk.

On such a hard drive, data is fragmented and stored in multiple locations. As the drive read and write data sequentially, it takes a lot of time to read a file if the file pieces position on different locations. In response to this trouble, here comes the disk defragmentation, which can rearrange the chunks.

Why You Should Never Defrag Solid State Drive (SSD)

Nevertheless, unlike hard disk drive, solid state drive has no the moving parts, not matter the spinning disk or moving head. So, many people are confused about the necessity of defragging a SSD. As a matter of fact, it is unnecessary and even you should never perform it. Now read on to get the actual reasons.

How Solid State Drive Works

In contrary to hard disk drive, solid state drive has no moving parts. It is entirely built by electronic circuitry. Therefore, in a solid state drive, no disk spins and no drive head moves around when reading and writing data. The disk spin and head Also, solid state drive works based on the flash memory that makes it to access the memory randomly unlike sequentially on HDD. Hence, it can perform much faster than the hard disk drive.

Unnecessary to Defrag Solid State Drive

The main reason why we defrag a hard disk drive is to improve the performance of hard disk drive. However, as what mentioned above, compared with hard disk drive, solid state drive has been able to work far more quickly. Moreover, the new generations of SSD always comes with TRIM feature enabled, which can clean the file pieces as soon as possible. In this case, obviously, it is not necessary to defrag a solid state drive.

Defragging Can Shorten the Lifespan of SSD

Furthermore, defragging can hurt a solid state drive. Flash memory used by solid state drive has a very finite lifespan. Solid state drive comes with a limited write and read cycles. It means, the more you write to a solid state drive, the shorter its longevity will become. Disk defragmentation is a procedure of reading data from one place and write it to another. Therefore, if you defrag a solid state drive, you will perform thousands of write operations each time on the drive. In this case, it can speed up the degradation of solid state drive and lead to its wear and tear. As long as the drive fails, all of the drive data will be corrupted too, such as damaged PST and so on. Therefore, you should never defrag a solid state drive.
