    First Power Nap not supported, now if this is true, it is being handicapped.

    I hope this is not the case

    This is nonsense.

    3 gigabit = 384 megabytes.

    The SSD in the Retina Macbook Pro exceeds 384 megabyte/s transfer speeds.

    It won't hurt to do some basic math instead of taking everything you read online as fact.

    And I said the non retina pro...not the retina pro.

    Sorry, must have glossed over that bit.

    Still, I'm pretty skeptical about this. Previous release of the MBP had the 6Gb link, can't think of any reason for them to source the much older 3Gb link (do people even still make it?)

    Yes it would be a step backwards if this was true.

    Just wondering, if this is the case, would you be able to open up the MBP and simply check to see if the hard drive cable is SATA 2 or 3 or do you specifically have to run speed tests?

    Oh come on! Why would they wanna downgrade an upgraded computer. There has to be some kinda misunderstanding.

    I took the Intel 520 SSD (sata 3) out of my 2011 MacBook Pro 13 inch, put it into my new non-retina MacBook Pro 2012 15 inch and re-installed Lion. I then tested the SSD speeds using Black Magic. I get about 440 megs/sec read, and about 230 megs/sec write. This is virtually identical to the speeds I received in my 2011 MacBook Pro.

    you gotta be careful with speed tests.

    on my windows PC I have an Intel 520 180GB with 560MB read 520MB writes and some of my benchmarks I ran wouldn't even come close to that. I had to run a specific benchmark application. I was getting dismal 200MB read and 190 write. Ran another benchmark i think it was Atto and I got the 560/520 the SSD is rated for.

    Benchmarks are sometimes not accurate.
