Hard drives are often configured to spin down when idle for a certain time. This can cause many spinups and spindowns per day. So I don't buy this at all. But I don't have supporting evidence that back up this notion.
- Wowfunhappy 2y ago> Hard drives are often configured to spin down when idle for a certain time. This can cause many spinups and spindowns per day. I was under the impression that this was, in fact, known to reduce drive longevity! It is done anyway in order to save power, but the reliability tradeoff is known. No idea where I read that though, I thought it was "common knowledge" so maybe I'm wrong.

- turnsout 2y agoI think NAS systems in particular are often configured to prevent drives from spinning down
- max-ibel 2y agoThere seems to be a huge difference between spin-down while NAS is up vs shutting the whole NAS down and restart. When I start my NAS, it takes a bunch of time to be back up: it seems to do a lot of checking on/ syncing off the drives and puts a fair amount of load on them (same is true for CPU as well, just look at your CPU load right after startup). OTOH, when the NAS spins up a single disk again, I haven't notice any additional load. Presumably, the read operation just waits until the disk is ready.
