I have the 2010 Macbook Pro (MacBook Pro 6,1). I'm about to pull the trigger on the dual disk drive upgrade. I'll be moving my current HDD to the optibay and the drive is SATAII. I'm unsure of which SSD to purchase. The SATA II and SATA III for 128gb and 120gb is roughly around the same price. But, I want to make sure it will be compatible for my computer. If it won't be able to utilize the SATA III, then obviously I won't purchase. Thanks so much.
