I am going to use a 2 TB Gold HDD in an acoustically-controlled environment for low frequencies (<100 Hz in our case).
Actually I find vibrations @ 90Hz caused by a 3-yrs old Green HDD. I also found some similar case in other HDDs, always at 90Hz. Vibrations are measured as acoustical noise transmitted by floor by a microphone 2 meters away from the source.
- It seems that 90Hz is a common frequency for vibrations stemming from some (or all) of these devs, isn’t it?
- Do exist specs about Gold (or 2TB Gold) HDDs vibrations? I actually find acoustic specs - which are excellent of course. Or, alternatively, can I be confident on the fact that Gold 2TB HDD will create neglectable vibrations?
