Question about WD Red Plus

Good evening, I'm thinking about getting a NAS and I'm strongly hesitating between the WD Red Plus 6to and WD Red Plus 8to, I've seen in many comments that there could be a difference in dB? do the 8to really make much more noise than the 6to or is it the same thing? I'd like to leave my NAS on a piece of furniture in my living room and I don't want to be disturbed by the noise from my hard drives (if the noise is almost the same I'd take 8to). Thank you for your help
