In Jan. 2020, I bought a Toshiba External Hard Drive, 2TB as the external storage for Xbox One S. Because the games are bigger and bigger. I feel the internal 1TB storage will be full soon.
You can still buy it on Amazon.ca. It is $89.99 now.
I found the old picture which I took before I open the box.
These are its recent look.
I am also using HD Tune to check the information on it.
