Hello all, I have a MacBook Pro 15inch late 2008 model. http://support.apple.com/kb/SP499?viewlocale=en_US I currently have a 320Gb 7200rpm Serial ATA Hitachi hard drive. I'd like to buy a new HDD of 500GB 7200rpm and get it installed. I'm concerned about compatibility issues. I have looked around I see that some Hard Drive SATA 3G interface. Would that be compatible with my mac ? Are there any other elements I have to watch out for compatibility ? Thanks for reading !
