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 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.
