Hello everyone. I'm looking to purchase the Non-Retina 15" MBP with the 1GB Video Card. I have a question in regard to the factory HDD that comes with it. If I select the HDD to be the "750GB Serial ATA Drive @ 5400 rpm", will I be able to move that HDD to the optical bay with a data doubler kit? There are no specs on which exact model HDD the 750GB is, so I was wondering if anyone knew. I know there have been issues in the past with using a 6GB/s HDD in the optical bay slot, and I'm not even sure if the factory 750GB is in fact 6GB/s. Thanks.
