WD Blacks are noisy no matter what, i personally don't recommend them unless you do need them. WD reds will have slightly lower specs, mostly on the latency, but it would still be my suggestion, although recently some people have also express that the reds having high seek noise on newer models (i haven't experience it). But this is something you have to decide on your own, for me 7200rpm drives are no longer recommended, specially with SSDs, but each of us have different needs and only you can decide what we sacrifice between performance and noise.
In time if you need more storage, i would suggest to consider an external NAS that you can place it where you cant hear it and leave you pc without hdds, todays high end consumer offerings are pretty nice, i like a lot Synology and Qnap, but you can build your own if you wish, even with multiple lan ports to sustain higher throughput over the networks.
