Hello,
I do not understand. The 12 TB and 14 TB are 7200 rpm, the 6 TB is 5400 rpm. Doesn’t the noise level depend on the rpm?
According to the WD documentation:
12 TB (WD120EFBX) or 14 TB
Iddle: 20 dB SeeK: 29 dB
6 TB (WD60EFZX)
Iddle: 25 dB SeeK: 30 dB
So far, I didn’t want to buy a 2 bay, 2 x 12 TB HDD because I thought it would be noisier than a 4 bay, 4 x 6 TB HDD.
What is the truth?
db is also not a totally objective value of how you will “feel” about the noise. Higher pitched sound might be 5db lower, but feel more disturbing. The regularity of it is also important, as irregular sound will feel more disturbing too.
