Defrag has been running for almost day now.

Is it worth defragging to get space back or is defragging ssd not
going to
gain much space when it finally finishes.

With modern OSs and drive sizes, defragging doesn't recover that much
space. But the main thing is, defragging on SSD drives might
significantly reduce their life, as they have significantly fewer write
cycles than HDs. If you really want to defrag them, _move_ their
contents to another drive (preferably an HD one), then move them back:
this will only involve one write (for most of their sectors; two to
their directory sectors). [Obviously if one of them is the OS drive, you
can't move all the files in this way, but it may still be worth doing.]

It's almost certainly worth reviewing what you're storing whe do you
really have 512G of material that you want SSD-speed access to?


It's really not necessary to defrag an SSD as their seek time is so
close to Zero that not much would be gained and some life would be lost.
