Hi Intel.
There are many Mac computers with Nvidia MCP79 chipset (Nvidia MCP79 is present in many models of iMac, Macbook, Macbook Pro, Macbook Air).
Nvidia MCP79 have SATA II controller.
There is well known bug with SSD based on SandForce SF-2281 and any Mac with Nvidia MCP79. SSD negotiated Link Speed is 1.5 Gigabit (SATA I). But it must be 3 Gigabit (SATA II).
OCZ already have fix for this issue (for their SSD):

Corsair works on this issue (they have SSD based on SF-2281).
Patriot Memory works on this issue (they have SSD based on SF-2281).
Intel 520 SSD have same issue.
Intel will you fix this? Talk to Apple or release fix by yourself, but you must do something, because Intel 520 SSD with 150 MB/s read/write speed on Mac (with Nvidia MCP79) is indecent.
Solved! Go to Solution.

Thank you all for posting,
I am sorry for the inconvenience.
Please note that the compatibility between different devices including (but not limited to) SSDs and Apple* products is very specific. Therefore, we recommend you to contact Apple* for a list of validated Intel® SSD models that can be used with their products.
Will the Intel® SSD work in my MacBook?

hello. What is the status for this situation? Has anyone from intel responded? We need an update. Intel should provide a fix for this so we can enjoy the product at sata 2 speed. Currently I have sata 1.

Hi,
I bought two Intel 330 SSD drive one for my iMac and the other for my Macbook pro. All of them works in 1.5MBps speed. Have to have a fix for it. It is very disappointing.

Same problem here, just fitted an Intel 520 in a MacBook Pro mid 2009, only 1.5 Gbps speed. Very strange Intel has no fix for this. Can i give the drive back?
