Also, for those who use Windows 8, it seems that most of you already defrag your SSDs:
http://www.hanselman.com/blog/TheRealAndCompleteStoryDoesWindowsDefragmentYourSSD.aspx
TRIM is not defrag. The only way they're comparable is that TRIM is good for SSDs and defragging (not too often) is good for HDDs. They're both maintenance tasks, that's where the similarity ends.
SSDs work completely differently from HDDs, and so therefore any (appropriate) maintenance work is going to be respectively different.
If you click on 'optimise' for an SSD on a properly configured Win8x install, it even says during the optimisation, "x% TRIMed".
The author's conclusion completely negates the entire article. Instead of spending a whole article talking about "kind of defragging", they should have just clued up in the first place and posted a few helpful articles regarding how SSDs work, the write performance penalty to a page that already contains data, and how garbage collection and TRIM works.
Furthermore, if they're going to make claims like "if an SSD gets too fragmented" and quote someone, then they should cite their sources, preferably with a link to a more enlightening article. I have a feeling that the author is mixing in the quirks of NTFS together with the maintenance techniques of storage devices when they ought not to be, but without any actual technical information for the claim or any useful source, it's pretty meaningless.
article said:
In the old days, you would sometimes be told by power users to run this at the command line to see if TRIM was enabled for your SSD. A zero result indicates it is.

Congratulations author, incorrect again. Furthermore, it wasn't ever correct. So before you embark on your next "real and complete story", fact check first!
When I attempted to educate myself the first time about the way SSDs work, I read this article:
