Hard drive upgrade options for a Series 3

I have a Series 3 (model #TCD652160) with a stock drive that is working fine. Looking to upgrade its internal hard drive to larger size. I have initially thought about going with a 1TB drive and I think this is the one to maybe get:

However, I am reading that this model can be upgraded to 2TB so may consider it. What are the WD models recommended for 1.5 and 2TB?
