Noise may be something to look for when you’re shopping, depending on where your server lives. I have 1 Iron Wolf drive in my NAS (that is in my living room), and it is way louder than the combined noise of 3 WD Reds next to it.
As for failures, Backblaze publishes quarterly failure reports that I always brush up on before looking for a new drive.
Totally. This person needs to put some mod podge on top to protect the paper and add weight.
