Start with a 2 TB Hard Drive
The PS4 Pro comes standard with a 1 TB hard drive, while the Xbox One S is available in 500 GB, 1 TB, and a limited supply of 2 TB models. Depending on who you ask, 1 TB may not be enough to hold a lot of games at one time without constant memory management. Somebody who buys one or two games a year may not feel the burn as someone who buys ten games a year.
While the PS4 Pro supports installing your own hard drive and the Xbox One S supports external storage, a bigger, included hard drive would be ahead of the trend that is rising game file sizes. Last Fall saw high profile releases with inflated file sizes. For example, Forza Horizon 3 needed up to 60 GB, Gears of War 4 required up to 85 GB, and Call of Duty: Infinite Warfare was up to 120 GB (included Modern Warfare Remastered pack-in and season pass content).
Project Scorpio could still be sold with different hard drive sizes, but a base level of 2 TB would be better than spending another $80 to $100 for an external drive that can only be used for the console or dealing with opening the PS4 Pro to stick a better internal drive in there.
