Irreplaceable 500GB internal HDD the only way to go for now.
In May, when the Xbox One was revealed worldwide, Microsoft said you’ll be able to use the console’s USB 3.0 port for external storage, used for game installations and downloads. But, nope, this won’t be available at launch.
“The future plan is for definitely to support external storage much like we do on the Xbox 360″, said Microsoft’s Larry “Major Nelson” Hryb during a podcast that took place at PAX.
“My understanding is that feature will not be there at launch because the team is working on some other things, but it definitely is on the list. I don’t know when it will come in though.”
On the other hand, Sony Worldwide Studios captain Shuhei Yoshida confirmed that the Playstation 4 won’t support external HDD’s

The Playstation 4 comes with a 500GB HDD, like the Xbox One, key difference being it can be replaced.
