In the maintenance of file systems, defragmentation is a process that reduces the degree of fragmentation.It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions (fragments, extents).
Defragmentation should be disabled on solid-state drives because the location of the file components on an SSD does not significantly impact its performance, but moving the files to make them contiguous using the Windows Defrag routine will cause unnecessary write wear on the limited number of write cycles on the SSD.

Defragment your hard drive. Also known as defragging, defragmenting your hard drive is a process that can clear up memory and help optimize your computer's performance. When you delete a file or ...
[b] The file system could defragment the disk immediately after a deletion, but doing so would incur a severe performance penalty at unpredictable times. Now, a new file called F, which requires seven blocks of space, can be placed into the first seven blocks of the newly freed space formerly holding the file B, and the three blocks following ...
A solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers, embedded systems, portable devices, large servers and network-attached storage (NAS). To satisfy such a wide range of uses, SSDs are produced with various features, capacities, interfaces and physical sizes and layouts. [4]
In order to avoid this, the allocator may, instead of failing, trigger a defragmentation (or memory compaction cycle) or other resource reclamation, such as a major garbage collection cycle, in the hope that it will then be able to satisfy the request. This allows the process to proceed, but can severely impact performance.
TRIM can take a lot of time to complete, depending on the firmware in the SSD, and may even trigger a garbage collection cycle. [ citation needed ] This penalty can be minimized in solutions that do batched TRIMs and/or periodic TRIMs, rather than trimming upon every file deletion , by scheduling such batch jobs for times when system ...
