I built myself a NAS a few months ago. Nothing special, using Unraid, four 8TB HDD's on array and one 4TB NVMe for cache, with HDD's set to spin down after idle time for power savings considering I rarely access them (cache drive helps a lot). But I'm wondering how much wear and tear I'm putting on them spinning them up and down every so often. Is it fine if I'm spinning them up once or twice a week at most?
