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 document.

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 3 Gb/s transfer rate calculated
according to the Serial ATA specification published by the SATA-IO organization as of the date of this
document. Visit www.sata-io.org for details.
