Is it unwarranted? Have Chinese tech companies turned a new leaf in their collective InfoSec practices?

Conversely, has Intel had a history of consumer privacy violations?

Maybe yeah. Also got the sense from the strong opinions that this is a preexisting debate, presumably in the context of continuous workloads or cached arrays with minimal spindown intervals. In that context it’s true that rotational disks still often win in energy efficiency and robustness (assuming we’re comparing them to consumer SSDs and not the latest enterprise u.2 stuff that’s rated for continuous work).

Not sure what everyone is arguing about here. Clearly SSD is better for intermittent r/w, whereas HDD can be more efficient at continuous r/w (especially in terms of watts/TB)

Just looking at specs should be enough to see that. SSDs can idle in ready state at close to 0 draw (~0.05w) whereas HDD requires continued rotation to remain ready. So consider an extreme case of writing for 1 minute then maintaining ready state for the rest of the day. For that the SSD will be far more efficient, obviously.

I don’t know, but I’d guess the buffered chipset controller has more stability during certain power state transitions.

Dammit, I came here hoping to see at least one “I have a very special set of skills.” Oh well.

Yeah I’d cut bait, rebuild from latest tapes. But also…

I’d put the corrupted backups in an eye-catching container, like a Lisa Frank backpack or Barbie lunchbox, to put on the wall in my office as a cautionary tale.

Nice, sounds like you narrowed it down.

You can leave turbo boost on and make more subtle adjustments using command line utilities like cpufreq or with GUI-based unraid plugins like this one.

Before spending time fiddling with settings though, you might try using /sys/devices/system/cpu/cpu*/cpufreq/energy_performance_preference to set one of the built-in profiles like balance_power. If you do need to make manual adjustments, I would try lowering max clock speed first.
