What is the maximum internal hard drive configuration on this model?

I am looking to upgrade the internal Hard drive to 1TB or more. Just wondering if there is a limit to the size of hard-drive one can get? Thanks

I'm pretty sure Chris is wrong on this one. Here a quote from OWC, looks like the 12.5 mm will work fine in your model: 1.0TB WD Scorpio Blue 5200RPM SATA *12.5mm* HD with Advanced Format Technology - Fits all Apple MacBook/MacBook Pro 'Unibody' Models (13/15/17"), MacBook Pro 'pre-unibody' 17"

Most MacBooks only support 9.5mm drives, so I assumed that that applied to this computer as well. However, I haven't been able to find a definate answer. Also, this forum references the same drive on Macsales/OWC that you do, yet also says that the computer will only accept a 9.5mm drive. Perhaps OWC is wrong.


Actually, after looking at the answer in that link, I just saw that it has two people saying he is incorrect, and that the computer does support 12.5mm drives. + For correcting me.


Actually Chris, I cheated on this one. I've installed a 12.5 mm drive in a 13" Unibody, so I already knew ;-)

You can install a 1TB 2.5" SATA drive in your computer like this one. Also, if you're willing to lose the optical drive in your MacBook, you can install a second 1TB hard drive in place of your DVD drive using an Optibay.
