Pro tip: Defragmenting only works on spinning drives because it puts the data nearer to the spindle so seek times are shorter. Solid-state drives wear out faster if you defragment them, since every write involves a little bit of damage.

well, defragging my ssd was the only thing that let me shrink the windows partition safely when i dualbooted... tho maybe thats just windows being funky

Defragging an SSD on a modern OS just runs a TRIM command. So probably when you wanted to shrink the windows partition, there was still a bunch of garbage data on the SSD that was "marked for deletion" but didn't fully go through the entire delete cycle of the SSD.

So "windows being funky" was just it making you do a "defragmentation" for the purpose of trimming to prepare to partition it. But I don't really see why they don't just do a TRIM inside the partition process, instead of making you do it manually through defrag

i used Defraggler, after nothing else worked to allow diskmgmt to shrink it, including all the normal stuff like disabling page files, snapshots, etc. it shows me how it was reordering parts of the ssd.
