I got an iMac 2017 27 " w/ 2 TB fusion drive and an iMac 2019 27"w/2TB fusion drive. 2017 is on High Sierra 2019 on Mojave. I wonder why 2019 has HDD sound heard in silent environment but 2017 has no sound at all. Any explanation?
Maybe different models?No, They both are Seagate 2 TB HDDs.
I wouldn't say that it is not important.I know it is not important but still wondering why there is a difference between 2 disks.
You may be right about sound deadening material @vertical smileI wouldn't say that it is not important.
It could be a sign of trouble in the future.
I wonder if the 2019s have less sound deadening material that would cause the sound to be different?
