VBoxManage.exe and Windows 10

Why are you even trying to mess around at this level? It doesn't sound like you know enough to do it safely, and a mis-step could corrupt your drive. If you're doing this because you are under the impression that bypassing filesystem caching will give you a faster drive then I'm afraid that would be very wrong.

Thanks for the tips and warnings. Yes, I really do this in order to speed up the virtual OS.
I understand that the performance gain will be small. But I have already installed the system and looked at how it works a little. With 1.5 gigabytes of RAM and 2 processor cores allocated to it, it works faster than before.
I'm not going to do something supernatural. I just need a stable Linux virtual system.
So again, thank you very much for the clarification.

Raw access could...

Not at all...

Ou... Happy new year. )))

I understand that the performance gain will be small.

In fact the "gain" will be negative. Anything else you see is placebo.

A "raw" disk is still a virtual drive, it goes through all the same VM abstraction layers as before, the only layers skipped are some host layers like caching that actually boost performance. So I see no possibility that your observations could be correct.

Yes. You rightly noticed. Logically, I understand this. And after working with the system for a while, I really noticed that the speed of disk access did not change.
