Hey there! I own an early 2011 MBP 15" and ordered it with a SSD 128GB. I will upgrade my Optibay with a 256 SSD in the near future... At least that was my plan. I was just wondering, if maybe the Drive that I would buy now might be more powerful (or better, however), so that it would make sense to put the OSX on that drive and put the original 128GB SSD in the Optibay...? I was looking at either of these: (good idea?) Crucial M4 Samsung Any difference in the Drives? Basically: New SS in Optibay, or the Apple 128GB in Optibay.? Thanks in advance!
