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.

      I agree on the “nonsense” part, as I’ve had none of those issues for over a year using this drive. Shit has been amazing. Also, I appreciated the lecture. I didn’t know any of what you said, so thank you. I did try xfs myself, but for my use case, I didn’t see any difference at all. Like nothing. I’m just a casual user who gets into the terminal some times, but that’s about it. So, btrfs works wonders for me with those sweet snapshots. Don’t know if xfs has snapshots, too, but I’m familiar with btrfs and timeshift, so I stuck with it.
