    Do I need to defrag my Hard Drive?


    I have this SSD hard drive:

    Samsung SSD 650 Series 2.5" SATA 120GB | for Business

    Do I need to defrag it? If so, what do I use to defrag it and how often?

    No, I would not recommend it.

    So leave it alone forever?

    Does Windows 10 automatically defrag it? If so, do I need to DISABLE W10 defrag?

    You can let Windows optimize your SSD. It WON'T defrag it in the sense that you're probably asking. More details here: http://www.hanselman.com/blog/TheRea...ntYourSSD.aspx

    I checked Defrag in my W10, and it says it's defragging weekly automatically. Should I turn it OFF completely, or change it to monthly?

    I tried that on mine and it took less than 1 second. I do not believe it did anything. Turn it off. If you want to try do in manually.

    It's NOT defragging it unless Windows has it misidentified as a spinner. If you trigger it manually, it's ONLY doing TRIM, hence the quick execution.

    Never defrag an SSD, it would only damage the SSD thus shorten its life time.
    Trimming is however useful for SSD's, but not really necessary.

    Per link in post #4 assuming you found it TL;DR -

    Conclusion

    No, Windows is not foolishly or blindly running a defrag on your SSD every night, and no, Windows defrag isn't shortening the life of your SSD unnecessarily. Modern SSDs don't work the same way that we are used to with traditional hard drives.
    Yes, your SSD's file system sometimes needs a kind of defragmentation and that's handled by Windows, monthly by default, when appropriate. The intent is to maximize performance and a long life. If you disable defragmentation completely, you are taking a risk that your filesystem metadata could reach maximum fragmentation and get you potentially in trouble.

    I totally agree with you on this. As a matter of being cautious, I do not let Windows do anything automatically.
