>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

It's not just about volume, but about noise profile. Sounds of equal power can be perceived very differently due to which frequencies they contain.

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").

There's a solid technical reason for that though, as ISPs have no control over the performance of your connection's remote part. Sure, it leaves plenty of room for abuse, but this is a necessary disclaimer, not some slippery marketing.

It seems like they want customers to compare their 7200RPM drives to competitors' 5400RPM ones, but the power consumption numbers in the datasheet show the actual differences.

For many years, the WD Green series didn't even specify the RPM.

I hate marketing...

I was expecting to read that 2x the heads would be marketed as spinning 2x faster, but ... it seems they are selling 7200 rpm drives as 5400.

There might be more power consumption, but in this case they are selling you a faster drive.

I kind of think this should be ok.

I wonder if mustang guys ordered a 6-cylinder mustang and got the v8 - would they complain about gas mileage?

That's what happens when you have little competition. Right now the high capacity, non-SSD hard drive market is a duopoly between WD and Seagate. Customers have little choice.

SSD volumetric capacity already exceeds spinning disk, and we're just waiting for the price to come down. The horse's dealer's competition wasn't more stables, it was the car.

SSDs expire, large long term r/w storage where speed isn’t important rust still wins

More power consumption on its own should be enough to make it not ok.

There’s also heat, noise, and drive lifespan.

Do people order 6 cylinder mustangs because that’s what they want or because they can’t afford the 8?

Why wouldn't they? They were fraudulently sold a vehicle that didn't meet the claimed specs.

After all this news of false advertisement and lower quality drives from WD, I'm glad I bought Seagate drives, even if only because Amazon had a big fat discount on Barracudas the day I was shopping for some spinning rust.

Seagate mea culpa'd afterwards, but they still tried to pull the same crap with SMR until they were caught.

There's an order or two of magnitude less data and benchmarks on the Toshiba drives, but I just bought Toshiba 6x6TBs for a NAS build because I couldn't stomach buying WD or Seagate (or HGST which is just WD now).

EDIT: Forgot to say, the drives have been great. It's only been 6 months or so, but they've been performant, no bad sectors yet.

If I bought a Prius and they gave me a V8 I sure as heck would.

Mustang owners might be an exception but I would be upset if I was hypothetically sold a V8 Toyota Camry when expecting a four-cylinder, even if I only paid the lower price.

I have a very standard commute where I drive boring and defensively. I enjoy cars as much as they get me from point A to B. There would be no benefit for me spending extra money despite the "better" engine.
