Seagate Barracuda shows 5900 rpm instead of 7200

A couple of days ago I bought a 2TB Seagate Barracuda hard drive, advertised everywhere as 7200 rpm. I tested it yesterday with the CrystalDiskInfo tool, I noticed that the RPM shown was 5900RPM instead of the 7200RPM.

I wasn't able to use any other tool to check the drive.
Is this an isolated problem? I couldn't find anywhere if this drive works while idle at lower RPM.

  It could be that the drive has a variable speed motor and at the time when Crystal checked it the speed was reported low. The first question would be: is this an actual problem, as in the drive is physically slow, or is it just that it is reporting an unexpected number? Knowing the transfer speed from the drive would give a better idea of whether there is something wrong. Try crystalmark.info/en/software/crystaldiskmark screenshots from both tools would be good.

  The 4TB drive in a close series is apparently 5900 RPM according to some sources and with other sources I can find 7200 rpm drives in a similar range (last digit of the model number is different). It appears that Samsung also want to move away from rpm as a speed measure as it is not mentioned in their datasheets. seagate.com/www-content/datasheets/pdfs/… it may just be that they give you an expected data speed and that is that.

Seagate's specifications say the "spindle speed" RPM for this drive is 7200 ± 0.2%. This is between 7186 to 7214 RPM. There's no mention of other speeds in other power states.

CrystalDiskInfo reports the "rotation rate" based on the drive's ATA8-ACS "Identify Device" data, specifically Word 217 (Nominal Media Rotation Rate).

I don't believe it's bug with CrystalDiskInfo because this is relatively simple, and a value of 5900 is common for other models. It's possible Seagate made a mistake, and wrote the wrong value, or a firmware update wrote the wrong value. It's also possible the drive is counterfeit, and the counterfeiters were lazy and only faked some values (such as the model).

How can we measure the RPM without relying on the Identify Device data? On another forum, someone named "fzabkar" posted a creative way to do this:

One way you could estimate the RPM is by examining the spread of data points in the graph of access time in HD Tune’s read benchmark.

For example, in the following graph you can see that, at the 450GB mark, the band of data points are about 8 msec wide.

The total access time is the time required to seek to the target cylinder, plus the time required for the target sector to pass under the read/write head. The latter time component can vary from 0 to one full revolution. Therefore this “rotational latency” will be seen as a band whose width is 8.33 ms in the case of a 7200 RPM drive, and about 11ms for a 5400 RPM drive.

  Hi, I really appreciate the effort in trying to help. I finally had a chance to do a more in depth research and following the Serial number found that in fact, the HD was ST2000VM003 instead of the mentioned above. I already contact the seller(Which is a highly rated one), just waiting to hear from them. Again, thank you.

Following the hard drive serial number, it turns out it wasn't a ST2000DM006, instead I received a ST2000VM003 which has lower RPM and R/W speeds but the same SIZE storage. See the pictures here-> https://imgur.com/a/yAZeMD2

So, the most probable situation is that the Company made the mistake to print a different label o the HD(as @Mokubai said before), or I am being part of a scam(which was my first thought)

Thank you.
