They are all about the same honestly when you're talking the same price/performance bracket. Don't get an enterprise drive they tend to be quite loud on seeks. IDK how you would really hear it though. I have 4 drives in my desktop and I can't hear any of them unless I turn my speakers off and my fans off and my NAS is the same way (more drives though).
What drive to you have that you can hear from another room?
Lol I know right, I've only had my stock CPU cooler hearable from a different room. Never a hard drive.
But like you said, they are pretty much all the same when under load, and if you get a new one, they aren't going to be loud. Yes, you'll be able to hear it, but what's the difference in that and your GPU fans making noise or CPU cooler making noise?
