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. RAID 0 (striped) accesses the full capacity of the drives. RAID 1 (mirrored) accesses half of the total
capacity for data protection. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one
billion bits per second.
