A:AnswerIt has 1 to 2 TB internal stock. Not sure I would want much more than that on a single drive. There might be a PCIe SSD's with larger storage but I don't think there is any internal room to add it. You'd have to toss what is there and rebuild. I'd just add external storage as that would be a better option in my view. I believe the RAM can be doubled but that means tossing everything you have to upgrade it. I think Geekom has a few units available with the 64GB ram.
