Due to the nature of issues with Sandy Bridge, Apple would have had to delay 2011 Macbook Pro production. However, they avoided this by "using chips that had been fixed". In reality, they stuck initial MBP buyers with a 3Gb/s Speed for an optical drive speed, and more recently produced (but SAME model nonetheless) MBP users with a 6Gb/s speed for optical drives. In order to establish the extent to which this occurred, please select the LINK speeds of your Hard drive and optical drive above, and the MONTH of purchase. As a reminder, PLEASE USE THE POLL (in addition to posting if you so chose to do so ) Thank you!
