Hell0- I am looking for a fast, reliable and affordable 500 GB or so SSD for my ASUS GT50V Laptop. I believe the controller is SATA II (300). Would a SATA III (600) SSD work with this system? Does it make sense to get that or is there a SATA II Model you would recommend? I need reliability and affordability (as close to $400 or less as possible) but want as much speed as possible as well. Thank you for your assistance to all, multiple opinions very welcome.
