I'm shopping for a new NVMe SSD drive for my laptop and with the second deciding factor being Linux compatibility, I'd looked up the names of specific drives in the source code of Linux and discovered that their controllers have quirks that have to be worked around.
Now, I figured out more or less how quirks affecting one of the controllers impact its functionality under Linux, but there's another controller that I have a trouble understanding how disabling the aforementioned command limits the functionality of, if at all; therefore I'd like to ask you all, under what circumstances is the command used by a host and can disabling it lower the performance or power efficiency of an impacted controller/drive?
To be clear, the quirk workaround I'm talking a about is NVME_QUIRK_DISABLE_WRITE_ZEROES.
A bit outside of my knowledge, but I understand that too be a long standing issue. Wiping issues are a good reason to encrypt a NVMe drive.
This page suggest the nvmi-cli has a secure format command that will do it. http://blog.pythonaro.com/2018/05/how-to-securely-wipe-nvme-drive.html?m=1
Hopefully, someone more knowledgeable will also tag me in their response.
