Anyone else running a 10T WD Purple drive who can confirm, it is normal for the drive to be heard? I am guess I am used to my SSD's on my main PC. Older NAS running 2TB red drives is 100% quiet despite running surveillance for a long time. New NAS/QNAP with with drive, I can hear when I stand in front of it. I guess the question is, if Purple drives are just naturally noisy? Thanks.
