    pparks1 - thank you for sharing the results.

    Just reinforces that windows does indeed defrag a SSD under certain circumstances.

    You are welcome.

    I think the main point to take away from here is that Microsoft is identifying properly that you have an SSD, and that an intelligent defrag is taking place on a monthly basis, however it's not unnecessarily shortening the life of your SSD drive. It's a balance between performance and long life. And honestly, I want performance day to day. I will have replaced my SSD in almost any circumstance due to capacity issues or new technology long before it craps out due to it's finite # of writes.

    I'm still running my first 80GB Intel X25-M G2 from Oct 2009 (Payed $250). It's my Windows 7 install from my previous computer build. I just disconnected it a few months ago, because I wanted to install Windows 10 on the box and figured that 80GB just wasn't going to cut it anymore. My new 240GB PNY drive was $60. But my Intel drive was over 7 years old without nary an issue.

    I'm not sure that I'm and some others now are as upbeat as you sound. Rather, there is no need to Defrag a SSD as it is bad. Rather windows should just TRIM. But with system restore enabled and optimize enabled on the machine, windows defrags which is not needed.

    I'm a systems admin for a living, both Windows and Linux. (and I have a MacBook Pro as does my daughter) I have earned Systems Engineer certifications from both Microsoft and RedHat.

    While I don't think that MIcrosoft is infallible, I'm pretty sure that their software developers and engineers have more skills and knowledge into this matter than I have. I'm of the opinion that they are aware of the popular belief that an SSD doesn't need to be defragged, and in fact should NOT be defragged. If you have System restore enabled, they are electing to do some defragging. I'm sure it's not because they are daft, or simply were unaware, I'm sure they have a reason for doing it.

    Like I said above, I have a 7+ year old 80GB Intel SSD drive still going strong. My wife has a Samsung laptop which is nearly 4 years old with a 128GB SSD in it and it's running just fine. My 256GB SSD in my MacBookPro that I bought almost 3 years ago is also running just fine.
    My experience shows that these sorts of things simply are nothing to concern myself with.

    Hi,

    How's defragging a SSD going to hurt it any more than doing say, an image restore ??


    And, BTW, has anyone actually defragged a SSD and enjoyed the difference in speed ?


    Oh, to add insult to injury, W10 defrags UASP connected SSDs as if they'd be spinners.....

    Urban myths and the internet, that's all you need.

    Just saying that when it comes to new tech, all logic seems to be flying out of the window.

    Cheers,

    I have read Scott's, at least I've read this one.
    The real and complete story - Does Windows defragment your SSD? - Scott Hanselman

    Seemed his conclusion was basically the same opinion I had. It defrags, and for a reason and it's related to performance. It's not enough to worry about.

    I have not read vadim's research.

    The real issue here is that MS has not officially released a KB article on why SSD defrag is a feature, why it is needed and how it is implemented. If the SSD defrag is there (as we know it is) there must exist a good explanation for why and how this feature is different from HDD defrag.

    Scott Hanselman is the only one who has at least tried to provide an answer to this, but he should not be the one posting "official" info on this. That is MS storage subsystem development teams job as they are the most knowledgeable regarding this matter and the y know how they have implemented this in code.

    Same goes for every issues or features Windows has. We need detailed explanations of what is going on, why it is implemented, how it works and some background info/facts on why it has been implemented in a particular way.

    If MS would provide the world more information, this topic would not even exist today. Everybody could read the KB article and just realize all is working as it should, or report further bug reports for further investigation and fixing.
