Engineer,
That's the wrong drive. The buy.com drive is a 12x/8x/32x drive, model CED-8120B, and the PDF you linked to is for an 8x/4x/32x drive, model CED-8080B.
Actually, it looks like LG linked to the wrong PDF from the 8120B web page! Anyway, bottom line is that this drive DOES have an 8 meg buffer.
