It is very hard to trust hard drive manufacturers these days. I have a few of these drives mentioned here https://www.seagate.com/www-content/datasheets/pdfs/ironwolf... with the specified "typical" noise level of 25 dB for seek and it is definitely much much more than that.

Synology forums have several threads like this: https://community.synology.com/enu/forum/1/post/130843

And I understand that these are different companies, but why I even went for Seagate was because of the CMR issues.

Yeah but they'd probably lie about that too, based on their recent track record.
