I think the TLDR is that Western Digital are selling faster drives marketed as being slower than they actually are, presumably due to lack of supply for the demand of the slower drives part of the market or something like that. You'd think nobody would mind until you remember some people want lower power and noise. Ideally these people would be buying based on those actual metrics, rather than the RPM as a proxy for…

Power use and acoustics are listed in WD datasheets, but I guess they might not be well comparable to values from other manufacturers.

The German-language forum that the article mentions has been doing some great detective work: https://www.hardwareluxx.de/community/threads/crystaldiskinf... The conclusion on page 4 of the above thread: > Non-Pro RED = 5400rpm according to data sheet > Pro Red = 7200rpm according to data sheet > Internal both 7200rpm and 120Hz. > Apparently all WD / HGST helium plates have real 7200rpm, no matter what it says. Simpl…

> What a world when you can't even trust the spec sheet. What's next, 10 watt class drives that pull 20 watts? 3-year class warranties?

Just like how internet speeds are advertised ("Up to 300 Mb/s").

Given the fact that they lied about RPM on their datasheets, why should anyone believe other pieces of information on their datasheets are correct?

Well, I'm looking for a 19dB-class hard drive. That class spans anything between 14dB and 60dB. That's the general noise class, you know.

This sort of misrepresentation should be outright illegal. Why does it feel like big corporations are just getting more blatantly evil these days?

This is already what they did with "KB/MB/GB/TB." Evil, but not any more blatant.

>That increase in noise and power is what got many users on the trail of Western Digital's fake 5,400rpm spindle speed in the first place

I'm amazed that there are people that would pick this up. I genuinely wouldn't notice a drive being a tiny bit louder/hotter

Earth does have a lot of people.

You might not notice a drive being a tiny bit louder/hotter, but you might notice if you've got an entire NAS rack full of 'em. Don't shout at your JBODs: https://www.youtube.com/watch?v=tDacjrSCeq4
