So I’ve put three of these new 14TB drives shucked from the WD EasyStores that I picked up from BestBuy in the last few days. I only have one of these drives in this array and for some reason, it sits at 100% utilization most of the time while it is checking of parity (I just created the volume). Sometimes it goes less, but most of the time it sits at 100%, unlike the other drives as you can see in this screenshot. It seems to perform just as well, its just odd that its always at 100%. I was curious to see if it was that drive so I tore down the array, swapped it for another drive of the same exact model and it did the same thing.
It must be just how these things are in a Synology so I wanted to share this with everyone in case this is something that may be undesirable for some. I was thinking maybe a firmware issue. Not sure where to look to see if there are firmware updates for the drives – I couldn’t find anything on WDs site.
