Queries on two different external drives to do with noise

Sorry for the late reply. Yes the 3tb drive works as its less than a month old. It came in a different colour box so i was thinking the same thing. The 4tb might be a newer design. its just weird the 3tb i cant even tell its on the 4tb on the other hand vibrates and clicks like the old school desktop hdds from years ago. I guess if they both work their isnt much i can do about it. Thanks for the comments.
