I had a 4TB Black for a short while. I tried to live with it but it was way to noisy and so I swapped it for a 6TB Blue, which is massively better. It is not the spin noise which is the problem, but rather the thunks and clunks you get as part of the drive access chatter. Really not worth it for the tiny performance increase if just using it as a storage drive.
Prior to the WD Black I had a Seagate FireCuda which was also 7200rpm. It was pretty much silent. I don’t know what WD are doing to make their Black drives so noisy.I'm sure 7200rpm drives still have value but in a desktop the noise is a factor worth thinking about.
