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.

If you re-read Grease Monkey's post, he wasn't doing it for speed.
Right, he was doing it to regain space, which is even worse. Defragging
doesn't reclaim space.
Then, there's the whole issue of not doing it to an SSD in the first
place. Bottom line, it was a bad idea from the start.
Just in case he needs confirmation on both of your points above, yes,
they are both correct.
Thanks, KB. ;-)
