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 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. Total accessible capacity varies depending on operating environment and RAID configuration. RAID 0
(striped) accesses the full capacity of the drives. RAID 5 accesses three-fourths of the total capacity for data protection. RAID 1 (mirrored) accesses half of the total
capacity for additional data protection. 4178-705023-A03 Jan 2009
