If you have done it a few times, it isn't going to cause you much trouble or harm your SSD.
What does defragmenting get rid of? ›Over time, adding and deleting files from a hard drive can make the data scattered, especially if it's running low on storage space. Defragmentation organizes the individual files, resulting in improved hard drive speed. Unused space is freed. Any unused space on a hard drive can be maximized by defragmentation.
Which defragmentation method is best? ›The SPACE method is ideal for the first defragmentation run on a system that has never been defragmented, as it requires far less free space than the COMPLETE methods. SPACE can also be used for regular defragmentation runs.
Does defragging speed up PC? ›Defragmentation puts those separated pieces of data back together again. The result is that files are stored in a continuous manner, which makes it faster for your computer to read the disk and retrieve the files you need, increasing the overall performance of your PC.

Since SSDs don't have moving parts, they're very reliable. In fact, most SSDs can last over five years, while the most durable units exceed ten years. However, how long your SSD will last depends on how often you write data into it, and you could use that to estimate the lifespan.
Defragging, also known as disk defragmentation, can cause problems because it is a process of rearranging the data on a hard drive or computer system. The hard drive is so large that the data it needs to store can become scattered, causing a decrease in the speed and efficiency of the hard drive.
Does Windows automatically defrag SSD? ›As a result, it will maximize the read and write performance on a hard drive, achieving twice or even better performance. Although, it often happens among hard disk drives (HDDs). Windows still defragments an SSD automatically to prevent the file system from reaching its maximum tolerance of fragments.
Should I defrag or clean up first? ›- Disk-clean up first, it removes junk files and lists space as occupied or empty.
- Defrag next: it lists clusters of files close to each other so the head can access all parts sooner, it also keeps empty clusters separate so removing junk files first helps.
Disk Defragmenter consolidates the fragments to one location on the disk drive. As a result, Windows accesses files faster, and new files are less likely to be fragmented.
