You want an SSD if you want it to be quiet, but an SSD of that size will be very expensive.
Data Hoarder
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
That's exactly the problem
Slower RPM HDDs will generally be quieter than faster ones, and consumer drives will generally be quieter than enterprise drives at the cost of long term reliability and possibly write speed, but in general HDDs aren’t quiet, and no one specifically makes quiet HDDs.
Moving parts make noise. You’re more or less looking for something that doesn’t exist. Instead of looking for a quiet drive, look for ways to sound-isolate your drive.
