This year I built a NAS . My focus was to optimize the price not the power, so I planned to go with a raspberry 5 or a raxda 5c because of their lower consumption. For what I gathered a RPI 5 and similar draw 3W idle and 12W at full power and a N100 based computer draw 9W at idle and 24W at full power (approximately of course).

But then I looked at the power consumption of the consumer grade HDD disks. 4 disks would add between 10 and 14W at idle and between 16 and 20W in operation, and suddenly the advantage of the arm based computers in power consumption is less striking.

Moreover you can find on AliExpress N100 mini-pc for 120€ with 16gb RAM and 512gb SSD. Aliexpress is risky but it was much less than the RPI5 with 16GB RAM or just a bit more than the raxda 5C 16GB , both without drive, case and power supply. And the raxda 5C would have been also bought in AliExpress so no almost as risky as my N100.

At the end, for cheaper to buy and not too much more expensive in power consumption I went with the mini-pc. I lost the possibility to use extension cards, especially the one that allows to connect up to 5 HDD, but a 4 port USB HDD dock proved sufficient for my needs.

>N100 based computer draw 9W at idle

That number seems suspicious. Right now my i5-6500T server is idling at <5W and an N100 is supposed to be even more efficient.

how did you get a 6500T to idle so low? Is that CPU power or total system power? I have a T part from the next generation, I don't remember the exact model. It's low but it isn't that low.

The processors themselves all seem to be pretty efficient at idle (there's apparently no real reason to get a T processor. It just caps performance). It mostly depends on everything else. The only place I know of to get this kind of info is this thread[0] where people have been building this spreadsheet[1]. Some threads on servethehome.com also report when some pcie cards have broken power management which can destroy idle efficiency.
