    Not sure if this is just a placebo affect, but I gave this a try this morning and my pro def seems to be snappier throughout the day. How to Disable SuperFetch in Windows 7 & 8Just a note after you hit disable I noticed it was still running until I hit stop..did not see that step in the post linked. Curious to see if anyone else feels snappier.

    Not using Surface Pro, but since I moved to a hybrid hard disk (Seagate Momentous) , and now to SSD (Micron C400), the Superfetch service has been set to Manual and is not currently running. So I can't compare.

    Update....I am convinced it is faster. I definitely notice it when swing down to close out an app. It seems to load apps quicker. Less time with the circle spinning around. I used to have an issue of a few sec pause when loading tweetro plus as the timeline updated, seems to come on instantly now. It still remains to be seen if this setting causes any other issues, but so far two days and everything else seems to work fine.

    Just disabled it, not too sure as to any performance benefits yet, but the one line in the article you posted made me do it. "this is even more true with SSDs (solid state drives) where the service actually becomes detrimental to both the system performance and health of the drive."

    I disabled it, but I can't really tell for sure if it made things more zippy or not. My Pro seems zippy.... but it is pretty fast anyway so it might just be a placebo effect lol.

    This makes me think changing superfetch may not be advantageous.

    I have researched high and low... and I am convinced that it should be left on. You'd think MS's MSDN would have a definitive explanation but they don't. They DO however say this:

    Results for the On/Off Assessments

    So yes, the reports of SuperFetch working differently in Win8 are true - whereas before it was a one-way pipe (moving frequently used data from disk to RAM) in Win8 it works in both directions and is used to send RAM to disk (hyberfile) as well!

    One more thought.... It is possible that Superfetch is also quite useful for micro SD cards, since this type of memory is quite a bit slower than SSD. I don't have one yet so I can tell for sure

    I've read on some microsoft boards that windows 8 sometimes leaves superfetch, defrag etc enabled even though it detects an ssd. supposedly it is smart enough to know, even with the features enabled, to not use these services if an ssd is present. if true, the speed difference is probably just a placebo effect but I'd imagine disabling the service might use a little less memory.
