Apple has released a firmware update that enables 3 Gbps on the Macbook Pro 13″. I just updated it and its showing as 3 Gbps in System Profiler.

@JohnnyC: Do update us on what you find after your conversation with Apple? Your research suggests that Apple could fix the issue later.

One final interesting note.

The Nvidia MCP79 series definitely supports SATA II. I found an article as far back as early 2008 confirming that detail.

PDF below for the MCP79 AHCI – on page 15 you will find in bits 23:20 the encoding for the interface speed 1.5gbps / 3.0gbps / 6.0gbps. Looks fixable in firmware (according to a post on MacRumors), and hopefully bumped to 6.0 gbps if and when this magical fix ever becomes available.

Well, crap. I just got the new 15″ MBP, and I even shelled out for the high-end model. To know that I paid a premium for a “Pro” machine that has outdated technology inside is infuriating. (Though perhaps this is but one reason why the prices were able to be dropped across the board with this new release?)

I will be calling my local Apple store to discuss refund or upgrade options related to this issue (once I look into these claims a little bit more that is).

i agree that this does not sound good. i really wanted to buy now and upgrade to SSD drive once they become affordable.

would be great if you inform us through a comment here when it becomes clear as to the motivation and implications for those upgrading to fast SSDs.

for now, i am putting off my purchase.
