Question: My internal drives are showing for some reason as removable in windows (one is SSD and the other is an HDD) in Windows 10 Pro.
I read somewhere this can affect performance.
Why is this? Is this defined in the BIOS or in Windows?
Is it possible to fix this?
This is NOT the same as How can I remove the option to eject SATA drives from the Windows 7 tray icon? since that question is for Windows 7 and the solution provided works does NOT work for Windows 10.
Answer: The issue lies in your BIOS, and has little to nothing to do with Windows. Check if you can manage your SATA devices, and Disable the Hot Plug function.
