    wondering about this last option in this picture:

    is there any benefit at all in terms of performance by checking this? and what exactly is the risk if lets say my power goes out with this enabled and computer is running/working? data loss? whatever I was working on at the moment or other, older data? possible bricked windows and need to reinstall the OS? or possibly worse in worst case scenario? :D


    stupid questions perhaps, but still interested!

    Loss of data, bricking the OS.

    About performance gain - hard to answer because it all depends on scenarios.

    Don't ... Your windows can go corrupt with just an improper shutdown. It looks great in benchmarks sure. But understand, even a BSOD while playing a game can render your OS unbootable, so not just power loss.I never understood why the setting is still there for anyone to toggle. It's not worth the risk.

    To be fair, any of the memory based SSD cache drivers do exactly this without setting the option, the risk of actual corruption on a ntfs file system is low.

    Possibly for those that use SSDs for fast as possible data processing, not as an OS drive.
    The source data is still intact and can be re-processed if it goes titsup.
    ie I have done database conversions where the limiting factor was drive speed.

    could also be cause MS completely forgot about seeing that setting it in the old interface and there trying to bury it with metro interface? o_O
