    Could not find it on this forum yet. FYI

    I came across this article while reading about maintenance on Windows 8.x.


    It's an article with some codes to run in PowerShell to show you excactly what Windows 8.x is running under the hood, and wow how was I wrongly informed that Windows 8.x BY DEFAULT did not - in any way - touch your SSDs with defragging command.

    Have a good read, Cheers...

    You clearly didn't read the update that was posted on 4-12-2014 on that article. They are linking to another article that states the conclusions are completely incorrect: The real and complete story - Does Windows defragment your SSD?

    Also there have been numerous tests where they write enormous amounts of data to an ssd. Those tests show that NAND cells will last a very very long time. The article fails to explain this properly.

    This is not a bug, it is an intended and well thought out feature of Windows. An ssd, like any disk, does fragment and that causes a lot of problems. Degrading performance, however, is not one of them (an ssd is fast enough for that). In this case the filesystem is a bigger issue. It's these kind of problems that are the reason why any disk will be (and should be) defragmented. So whatever you do, leave the scheduled maintenance stuff alone!
