Windows 10 ghi vào ổ đĩa gì trước khi đi ngủ?

I have noticed that my Windows 10 laptop takes around six seconds to go to sleep, during which the SSD’s activity LED is on. I imagine that Windows is writing something to the SSD before going to sleep.

I remember my Linux systems going to sleep instantly when I pressed the sleep button, which makes me wonder if I can do the same with Windows 10.

Given that Hybrid Sleep is disabled, what does Windows 10 do with my drive before going to sleep and is it necessary?

I imagine that Windows is writing something to the SSD before going to sleep.

That is correct. If there is any data waiting in the disk’s write cache, it must be written to the disk before the disk is powered off. Note that disk caching can be disabled so that everything is written to the disk immediately. This ensures that data is not lost as a result of a power failure, but it does reduce performance.

Turn Disk Write Caching On or Off:

1. Right-click My Computer, then click Properties.
2. Click the Hardware tab, then click Device Manager.
3. Expand Disk Drives.
4. Right-click the drive on which you want to turn disk write caching on or off, then click Properties.
5. Click the Policies tab.
6. Click to select or clear the Enable write caching on the disk check box as appropriate.
7. Click OK.
