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)
