Hi I have 2010 June mac pro. But since it's bottlenecked at SATA 2, my SSD is not getting the full power. Since I'm not really good at modification, I was just wondering if I can change all my SATA2 cables to SATA3 so my SSD can get SATA 3 speed. Or do I need an additional PCI slot card for SATA3 interface? How can I upgrade from SATA2 to SATA3 in the convinient way possible? Thanks for reading.
