Is it possible to upgrade the internal hard drive of the Xbox One to 6TB or 8TB? if yes, then what type of internal hard drive would you recommend that i should get?
Yes it is possible but extremely diffucult and not worth your time most likely. You have to flash the Xbox firmware onto the hard drive. The OS is on the internal hdd. I had a Xbox with a failed internal hdd and I just ended up getting a new one because of the difficulty of getting the OS onto a new hdd and it isn't guaranteed to work. Even people that professionally repair Xbox's told me that it doesn't always work. Why don't you just get a external?
