5W is still a lot if you add controller power requirements, and 5V->3.3V DC-DC conversion losses. Also I have one of those Power-Z Type-C <-> Type-C power meters, and even with less power hungry western digital nvme, it didn't fit into 4.5W. And it consumed the most power not even during initial write test, but during a minute after kernel reported sync() success so after everything was supposedly written to the device and no power hungry activity was needed. Then it jumped to 7-8W. I guess these dram-less nvme's do some reshuffling from faster flash to slower flash locations during idle time. Which is probably terrible for portable use, where you may want to sync() and then unplug the device once the OS tells you everything is synced up. Creating regular power loss situations during these reshufflings just feels like putting too much trust into nvme firmware, IMO. :D
