Hello everyone, I have a 2010 MacBook Pro with a SATA II (3gbps) port. I am looking to upgrade my stock HDD to an Intel 510 SSD (which is SATA III). I know that I will not get all the complete benefits of a SATA III connection, but I may swap this drive out to a computer that does support SATA III in the future (a little more money is not a big deal for me). I just want to know if there are any performance issues if I plugged in a SATA III device in a SATA II port. I've read mixed responses arguing that it will work perfectly fine (like plugging a USB 3.0 device in a USB 2.0 port) while others claim that a SATA II SSD will perform best on a SATA II port and that using a SATA III device on a SATA II port will cause problems. I just want to receive a definitive answer before making any purchase. Thank you!
