Windows 10: Windows writes files to memory first before moving them to the HDD?

I have been noticing this "weird" behavior lately, I noticed it when I attempted to decompress a very large archive containing many small files 2 days ago.
Basically the decompression speed was insane even for my my 7820x, between 150 and 200 MB/s.

After the decompression I noticed that my HDD was making quite a lot of noise for minutes after the decompression even though I wasn't running anything.
I then open the Task Manager and the Disk activity was indeed at 100%, but what's more interesting is that there were more than 2 GB of modified memory waiting to be written to the disk and this amount was slowly decreasing as the HDD kept writing. The 7zip process was nowhere to be found in the task manager.
I was able to replicate this by unzipping the same archive again.

This might be a neat performance improvement feature that allows the HDD to delay writes so that it can process them later when there might be less activity, but what if I lose power while are still in memory waiting to be written?

Currently I don't know if this is a feature or a weird issue, do you happen to have more info on this?

6233 Problem Record Video in card memory

Hi javasaad

It would be very slow writing video to memory card. Why not write to phone memory and use file manager to move it to memory card immediately afterwards?

 

The HDD is use to store data permanently, when a data stored or to be stored are always work on in system memory. Your computer uses RAM to load data because it's much quicker than running that same data directly off of a hard drive.

 

I believe it goes into ROM and then to the Hard Drive-Read Only Memory.

 

This is a design feature, more on how it works here....

Therefore I always use for external media "safely remove hardware and reject media", to prevent HDD or memory stick failure. Sometimes you will notice that it takes a while before blinking on the device stops and Windows says: removal is ok.
