Question: how much bigger is a tb than a gb?
Answer: A terabyte is equal to 1,024 gigabytes (GB), which itself is equal to 1,024 megabytes (MB), while a megabyte is equivalent to 1,024 bytes. All storage measuring units -- kilobyte, megabyte, terabyte, gigabyte, petabyte, exabyte and so on -- are multiples of a byte.
