Outside of occasionally using the "update and shutdown" option or shutting down the PC to swap parts or take photos for a tutorial, I always hibernate it. I'm a great candidate for this showcase because I hibernate my PC daily like clockwork. But if you want the long answer, let's crunch some numbers.Īgain, I'll use my daily driver machine to showcase things. Yes, it clearly adds wear and tear to the disk because you're writing extra data every day that you wouldn't otherwise write to the disk, but what does it mean relative to the lifespan of the disk? The quick answer: it doesn't matter. The million-dollar question (or at least the $300 question if you're trying to avoid replacing a premium SSD) is whether or not the extra writes matter. Here's Why It Doesn't Really Matter That Much Our file is 13.39GB which lines up nicely with our estimated 13.5GB value. Want to double-check that under real-world conditions? The next time you bring your PC out of hibernation, check the file size of the hiberfil.sys file located on your C:\ drive. If you have similar RAM utilization levels but only 16GB of RAM, you'll likely write about 6-8GB of data per hibernation event when you account for the compression. So, on average, every time I hibernate my Windows PC, I write about 13.5GB of data to the SSD. So our 18GB or so of RAM utilization gets mashed down to about 13.5GB before it's written to your disk. That's because since Windows 7, when Windows writes the hibernation data to disk, it applies a compression algorithm that reduces the file size. Once you have the value, in my case about 18GB, you have one last step. The manual calculation and memory performance check both show my system is using around half the available RAM. The RAM utilization fluctuated a small amount between screenshots, but you get the idea.
