user82890: If blocks were 2MB, and a 2MB block that is only 10% full gets confirmed, then how much additional storage is required on a full node?
I am guessing the correct answer here is 200K?
Thanks in advance for any guidance in this matter.

user208: Full nodes are not required to store blocks (they can be pruned). So the answer is 0.
If a 200 kB block does get stored, it takes 200 kB to store it.
