As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second(MB/s) = one million bytes persecond, megabit per second (Mb/s) = one million bits per second, and gigabit per second(Gb/s) = one billion bits per second.
