Hello guys,. Noob here and 1st time MacBook Pro owner. I recently purchased a used 2010 MBP with 4gb of ram and 320gb hard drive. It's a core 2 duo running El Capitan. The question I have is on the Apple site it says I can upgrade to 8gb. ram and either 500gb sata drive or 512gb SSD. Will it be possible to upgrade to a larger hard drive? Am I limited to 500 or can I swap in a 1tb drive?
