    SSD defragmentation in Windows 8


    I just found out that the defragmentation for SSDs works quite differently in Windows 8 - interesting.

    In Windows 8, when the Storage Optimizer (the new defrag tool) detects that the volume is mounted on an SSD - it sends a complete set of trim hints for the entire volume again - this is done at idle time and helps to allow for SSDs that were unable to cleanup earlier - a chance to react to these hints and cleanup and optimizer for the best performance. We do not do a traditional defrag (moving files to optimizer there location for space and performance) on SSDs.

    You never as never defragment a SSD drive, trim is there for that, the defragmentation will short the cells life .

    I think you did not read what it says.

    Thanks whs, it's very interesting info, I have already stopped Optimize service, I'm going to enable the service and see what difference it makes.

    EDIT: I think the defrag application ( it blinks and disappears) won't show up even after enabling Optimize service, Windows 8 recognises SSD and disables defrag.

    I just got BRAVE and run the optimization TWICE. It did the trims so fast, I didn't even notice the first run, and ran it a second time. It took about two seconds or so. I did a fresh install of Windows 8 back on 10/27, the day after the release. It appears there was not much to optimize.

    yes I read it, but since the subject is "SSD defragmentation in Windows 8 ", I think it's important to add to not make defragmentation on SSD

    That is correct. But I think everybody knows that.

    This is good news, system response is better with Optimize service in Auto than disabled, I don't care about the life of the SSD as the price is falling down each week

    I don't care also about my ssd they are Intel 5 years warranted, in 5 years they will be obsolete anyway.
