Good point. I looked mostly at the spec sheet from the manufacturer and for example the Samsung 870 Evo vs Seagate IronWolf NAS Drive. Side note, AFAIK NVME drives have a higher power consumption. Especially PCIe 5.0.

My NAS with 2 HDDs from Seagate has a total powerdraw of around 30-40w. And I don’t spin the drives down.

1. Latency of accessing files/loading times
2. Lifespan reduction because of spin up / spin down Head moves (the most common for head crash, as I learned from my Teacher)

Most of the power draw is from the hdds. I have the same issue. If you want less power consumption. Invest in SSD or SSD and HDD hybrid where you store quick access files on SSD and rare access on hdd (then you can spin them down with timeout of , let’s say 30-60 min). This should save some energy
