I put my MBP next to the new Retina MBP today, and although the new display was incredibly crisp, and normal usage distance, it's just not that much better than mine as I'd opted for the high res (1680x1050) display. I'd thought I could for a lot more on the display, but it's not enough of a difference to justify cost, so I'm sticking with this, and going to upgrade the HDD to SSD instead.
I've heard that some of the early 2011 SandyBridge models had a problem with the SATA controller and that they didn't actually support SATA III.
Is there a way to check this out without actually just installing one to see if it works?
Intel 6 Series Chipset:
Vendor: Intel Product: 6 Series Chipset Link Speed: 6 Gigabit Negotiated Link Speed: 3 Gigabit Description: AHCI Version 1.30 Supported
I see from the system info that it has a 6gb link speed, but obviously the standard HDD is only SATA II, other than that I'm at a loss to see how to tell.
