Yeah fair enough, but that's why they run idle instead of off when not in use, right? At least my NAS optimizes the lifespan of my drives while at the same time preserves power by keeping them running idle when not in use AFAIK. As soon as I access data I hear the drives spinning harder. My pc runs on SSD's as it is off during the night and downloading to SSD storage means rewriting bits all the time which wears SSD storage down, unlike with HDD's. So my NAS runs sonarr and radarr and automatically downloads everything by itself, directly to HDD's. But those HDD's are idle when I'm not downloading, because I'm not uploading because I don't use torrents.

But please correct me if I'm wrong. I'd love to improve my setup and the life span of my drives.
