 As used for storage capacity, 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 per second,
and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 6 Gb/s transfer rate calculated
according to the Serial ATA specification published by the SATA-IO organization as of the date of this specification
sheet. Visit www.sata-io.org for details.
