Be warned, I got an HGST drive for personal use, happy to pay the premium. It was quite loud, my wife commented from across the room "What is that?". A periodic loud "tick". Turns out it does some kind of calibration and you can't turn it off. Many reviews mentioned it, didn't even look.

I returned it.

WD blacks do that too, although it's more of a grunty, almost snort-like oink.
