Hi all, Just want to state first that the model I have isn't with 500GB Desktop drives it actually came with 4x1TB enterprise drives. Now that is out of the way, I wanted to know how can I find o...

I think you mean Red Pro. There are no 7200 rpm drives in the WD Red line.
The prices I see for the 4 TB Red Pro (WD4002FFWX) and the 4 TB gold (WD4002FYYZ) are the same - within 2 USD on Amazon on the moment. The specs are also nearly identical. Either drive should perform well.

We have already reached the conclusion of buying 4x4TB which would cost about $1000 CAD but I may just have to make it 5 to have a spare and off set the data temporarily to do the factory reset.
That would do it too - backing up to two of the 5 drives, and then doing a factory install with 3x4TB in place. You'll be able to restore to the resulting 8 TB data volume, and then add the 4th drive to get to 12 TB.
It is also nice to have a spare disk on hand.
Yea red pro - thats what i meant. Way to many damn variations now compared to the older days smh.
U said install 3x4TB first? I set up the NAS to be under netgears version of the raid w/e its called. Doesn't that version need a minimum of 4 drives?

XRAID. In your NAS it's a set of tools built on top of mdadm.

No. You'd need 4 drives for dual redundancy (RAID-6). But normal XRAID can start with one drive. The second drive added will convert the array to RAID-1, the third will convert to RAID-5. Those OS 4.2 expansion limits get in the way with larger disks though. Adding the last disk will fail if you start with 1 drive (exceeding the 8 TiB growth limit).
With 3x4TB as the starting point, XRAID give you an 8 TB volume (~7.2 TiB), and an expansion ceiling of about 15.2 TiB - close enough to the 16 TiB max to not worry about it. You could for instance upgrade 2 disks to 8 TB later on, to get a 16 TB volume.
