Will defragmenting the disk give you more space?
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.
Defragging does not save any disk space. What it does is rearrange the used parts of the disk so the various parts of each file are contiguous with each other.
By defragmenting the free space on your hard drive, you can improve Windows' performance when writing new files. You'll also help prevent new files from being fragmented.
Defragmentation organizes storage on your computer by consolidating files and other data saved on your hard drive. When there's not enough space on your disk to store an entire file in one place, the file is broken down into smaller pieces called fragments. Defragmentation puts those pieces back together.
To summarize, do not defrag an SSD
The answer is short and simple β do not defrag a solid state drive. At best it won't do anything, at worst it does nothing for your performance and you will use up write cycles. If you have done it a few times, it isn't going to cause you much trouble or harm your SSD.
Even if you interrupt the process somehow, it's not likely that your hard drive will suffer any harm. Defragging is one of the safest and simplest ways to care for your hard drive and ensure your PC is optimized for its best performance.
Because defragging only re-organises files, it will not free up disk space. It will require some space to do its work, resulting in higher disk usage until it has finished.
Free hard disk space
Drives without any free disk space cannot be defragmented. For the best possible results, at least 5% of the whole hard disk capacity should be free. Files larger than the maximum free and connected storage space, may not be possible to defragment, and if so only with several runs.
Defragment at Least Once per Month
As a general rule, any time your disk is more than 10 percent fragmented, you should defrag it. In Windows 10, Windows 8, and Windows 7, you can schedule defragmentation to happen as often as necessary.
Generally, you want to regularly defragment a mechanical Hard Disk Drive and avoid defragmenting a Solid State Disk Drive. Defragmentation can improve data access performance for HDDs that store information on disk platters, whereas it can cause SSDs that use flash memory to wear out faster.
How often should I defrag my computer?
For most normal computers, a monthly defrag of the hard drive should be fine. Windows users can simply use the built-in desk defragmenter utility on their machine. Run a quick systems scan and follow the instructions - the scan tool will tell you whether or not your hard drive needs defragging.
Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process.
Normally, a defrag operation will not cause data loss. Unfortunately, if there's a pre-existing problem, a defrag could bring data loss to the surface.
Open Disk Cleanup by clicking the Start button . In the search box, type Disk Cleanup, and then, in the list of results, select Disk Cleanup. If prompted, select the drive that you want to clean up, and then select OK. In the Disk Cleanup dialog box in the Description section, select Clean up system files.
If your computer has a hard drive 1 TB in size, 2 hours is within reason for a 7200-rpm hard drive. A 5400-rpm hard drive could take longer. I would let it finish. If you stop it, the defragment app will stop in an orderly fashion and nothing will be damaged.
Power Loss. Your computer is relocating data on the hard drive by erasing it and rewriting it during a system defragmentation. If the computer loses power during a defragmentation process, it can leave parts of files incompletely erased or rewritten. This causes the files to be corrupted and they may not be recoverable ...

Defragging will only help gaming if that game depends upon accessing maps and other data during use. It also helps the game to load faster. It doesn't improve framerates though.
Yes, you can pause it. But this is what the schedule that Windows wants to do is for. A teeny bit of automatic defrag once a week prevents a manual defrag that takes 24+ hours.

The short answer is, no. Defragmentation is not required.
Defragmentation is the process of locating the noncontiguous fragments of data into which a computer file may be divided as it is stored on a hard disk, and rearranging the fragments and restoring them into fewer fragments or into the whole file.
