    Hibernation ssd usage


    I normally do not use hibernation, but I have a pc I use to view my main pc and I am thinking about using hiber for it. Is the pc writing a lot of what is on the ram as it operates or does it just write to the ssd when I turn my pc off using hiber? I am kind of picky about use of my ssd that is not really necessary.

    Hibernation saves the state of the PC at the time you hibernate. There is no overhead while the PC is running, hiberfil.sys is only written to as the PC enters hibernation.

    Ok great. I was hoping that would be it. I was curious since the space reserved for hiber is pretty big, I suppose in case it would happen to be needed. I really don't have much for it to save, probably just browser, anydesk and the temp monitor program to start. Thanks for the info.

    When you activate hibernation it creates the hibernation file on the root of the boot disk, allocating as much disk as you have RAM, but that's it. During normal operation the file won't be touched at all nor will slow anything else down with unnecesary writes to disk. Only when you actually command it to hibernate it'll write your full RAM to disk.

    Besides, it seems you're worried about "wearing out" the SSD. Just don't, Normal SSDs can withstands many terabytes worth of writes without problems, and still be good to use, so a single shot of 8GB won't make a dent in its reliablilty. Don't fall for the "writes destroy SSDs" myth.
