I have had good experience with WD Black but these new WD Gold & Ultrastar drives are the latest and have newer technology and not to forget they have very amazing capacities.

Both are enterprise class HDDs from WD. These are meant for data centers with 24/7 (read/write) operations not to mention these are very expensive. An 18TB gold drive will cost upwards of 600$ within USA. That's like 100K+ PKR. If you import it then according to amazon it will cost you like 140K PKR.
As much good and long life as they are for their purpose, they are still mechanical drives and are prone to failure be it sudden or otherwise.
I don't think either of those are available in PK at least not in those capacities.
