I've never used the 3tb version but I have used both the 1/2tb versions and there as quiet as they can be for a mechanical drive, should really only be audible (fairly loud) if the drive is faulty or or is going to fail but I suppose it depends on what you consider as noisy.
You can't just compare brands and capacities. You have to compare exact models, which is why OP gave the exact model.

Looks like it's a 4 platter drive. That's towards the high end (typically the 3.5" drives are 2 or 3 platter), so yeah you should expect it to be a bit noisier (and run hotter).
Unfortunately, the only site I know which measured HDD noise in their reviews (Silent PC Review) hasn't done any meaningful reviewing in 8 years. So you'll probably have to just buy it from a store with a good return policy, and return it if it turns out to be too noisy for your needs.
I never found rubber washers to be very effective. I ended up suspending my drive cage with velcro cable ties. The HDD noise isolation boxes are supposed to be very effective too (though you have to be sure you buy a good one which gives the drive sufficient heat dissipation).
