Confused about the Write Zeroes command
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.
What if you try to wipe a NVME-drive for which this quirk is enabled by default in the kernel? Does that mean that even if you used something like the 'erase device' function in GNOME Disks on said drive, it would in fact not actually completely zero the drive? What if you use GNOME Disks to wipe a partition on said drive?
Or does this quirk refer to an entirely different operation?
