    Is it worth setting SEC NVMe Idle Timeout to 0 or just adding the option with default of 200 is enough?

    Hey Nick, :)

    Setting it to "0" will have the NVMe never power down from being idle.

    This may increase performance with the NVMe always on, but it may also cause the NVMe to heat up more.

    I'd say it would be worth benchmarking before and after while also keeping an eye on temps to see if it makes any difference for you or not.

    Yea I'll do that sometime. Since I use this machine for work I should be conservative. Is 200 ms quite long?

    You would probably never notice it.

    ok, I'll leave it at 200ms for now and can test it in my spare time.
