So recently I’ve been wondering “why my FW12 sometimes idles at 4.5W and sometimes at 6W” and noticed that with the higher power draw the SSD temp is over 50°C and at lower power draw it’s between 35 and 40. So it seems like this SSD kind of bugs out and stays in some performance state instead of sleeping properly.
I found out that some SSDs’ sleeping power state is a “non-operational” one and they can draw additional power to do something in the background and by disabling it with this command: sudo nvme set-feature /dev/nvme0 -f 0x11 -V 0x0 SSD’s temperature and power draw drop immediately. It gets enabled back after sleep and I’m not sure how that would affect SSD’s overall longevity. Performance wise I don’t see any difference.
