Should SSD's be defragmented

Ok, so if I'm getting the messages correctly, then I should turn off Trim. Also, is "hibernating" an SSD going to hurt it or not?

If you have an SSD you want trim on. Hibernating will not hurt an SSD, what it does is use space on your SSD and some people don't want that.

Forgive me, but this is confusing. I'm being told overall not to defrag an SSD. But is not TRIM in essence doing that once a month or am I misunderstanding something totally?

Yes. When hibernating, a computer writes a lot of info to the SSD, speeding up the time when it will wear out. There are plenty of posts from users on different forums stating that this is not true. However, PCWorld says that it is, although PCWorld does state that the wearing out of your SSD will take place over a period of years.

TRIM is an entirely different process than defragmenting. TRIM is how SSDs are optimized, defrag is how HDDs are optimized.

Ok, not to drag this out, so all would agree then to keep TRIM on and do not touch the SSD with any defragging program, such as Diskeeper etc.
By the way, has Diskeeper gone out of business, for I have not received any updates on this since 2012 I believe.

A lot of information on the Net is now outdated , look at the article's published date to see when it was written a lot of that info is essentially wrong today especially on Win10.

Trim is essential on a SSD ( why early on Company's provided utilities to do it ) to clean up the Drive internally after deletes etc are done , the internal command does not effect the SSD like a traditional Defrag as it writes nothing to the SSD , just changes the "pointers" so the SSD thinks it memory cells are empty etc.

The old habit of not letting a SSD hibernate was cos the 1st SSD's were only 60GB or perhaps 120GB and the Hibernate file is usually 1.6x the size of you physical Ram so if you had 8GB Ram you lost 12GB of your new 60GB SSD which made it a squeeze if you want all your Programs on the SSD too , not just the OS.

Windows 10 recognizes SSD's now and will not allow a Defrag , it does offer to Optimise them which is really the Trim Command being applied. it does it Auto and you don't really need to adjust it.

Good. Thanks for the helpful replies guys. This has been very helpful. If there are others who want to wade in with more comments, please do.
I'll not have Diskeeper kick in on the SSD but let Windows TRIM do its thing.

Thank you for the Interesting reply Layback Bear. I have a Samsgung 850 EV0 250GB sitting here on my desk not installed yet. But I can tell it's just raring to go. Being ignorant to this cute little tyke, I'm not sure any software comes with it so will allow TRIM to do its thing. Onions, pardon me, I mean opinions abound around but I've appreciated the advice you & the others have given. I think I'm going to just layback & give heed.
