My motherboard is Gigabyte GA-945PL-S3 and it has 4x SATA 2 ports. I have SATA 1 disk installed and it's slowing my system, I think it is because of its 8mb buffer. I want to upgrade or should I say replace this disk with newer one. For the future I want SATA 3 (maybe for newer motherboards).
I'm confused. If I'm planning to buy a SATA 3 hard drive to use on a SATA 2 port, should I should buy a SATA 2 hard drive for this motherboard instead or there is no difference?
