I would also very much like to see a photo of the packaging. Notice that the band of access time data points is about 11 msec wide. This corresponds to the time required for one complete revolution at RPM. The width for a RPM drive would be 8.
Can you post a picture of the packaging and where it says rpm? Wow fzakbar, lots of info. I have taken the links and will be reading them. What software do you recommend to read the drive? Nowhere else on the box or in the paperwork inside is the speed mentioned.
I need to see the whole box, so I can point out that it is indeed showing rpm for a green drive. But it still says rpm. Do you realize what you are looking at? In this case, it shows you which drives have rpm rotation speeds.
If you look across the rpm line you should see that the green drive does NOT have a check mark. That means that the green drive does not have a rotation speed of rpms.
So, the box is not lying to you. You just are not reading it correctly. If you were looking for a drive with a rotation speed of rpms, then you should have bought either a Blue drive or a Black drive, based on the chart on the box, itself.
The green drive has check marks for what features it supports. Post by ihartley » Tue Dec 17, pm. Post by storageman » Tue Dec 17, pm. Post by Moogle Stiltzkin » Tue Dec 17, pm.

That they have basically enabled TLER and eventually disabled aggressive unloading - and charged a premium for what was freely configurable. Note: they do have a longer warranty, that IMHO is worth the premium anyway. THIS I was astounded by. Given that the drive head "floats" on an air cushion that is created by the disk spin, how could they keep the head at the same distance when the spin speed changes????
Existing in name only; not real. Thanks for the recording and thanks especially for including the start-up, which makes it very clear what the difference was between off and on. There's a lot of background noise in the recording, but, because you michaelchiklis were able to get the microphone so close, the evidence is quite clear. This drive is definitely spinning at 7, RPM.
I've attached two screenshots which you can use as documentation; one that shows the audio spectrum with the HDD off, and the other with the HDD on. When the drive is turned on, there's very clearly a spike at exactly Hz See the "Peak" box in the screenshot. This corresponds to 7, RPM.
The Hz tone is clearly audible in the recording, and you can hear it increase in pitch as the drive powers up. There's no question in my mind that this tone is produced by the disk rotation. Hopefully this can resolve the question for you. The results so far indicate that some drives spin faster than what they are rated.
As long as they spin faster and not slower, I think the manufactures are not on the hook for anything. Sell a drive rated for and it spins at , that is a bonus because it is faster.
When they sell one rated at and it spins at , then there is a problem. It may be that some people would prefer a genuine RPM drive with the expectation of lower power consumption, less noise, and higher reliability. In any case there's no excuse for deceptive specifications.
