iMac 27 Late 2009; possible to solder&activate a third internal SATA?
the late 2009 Model doesn't have a 3rd SATA on board, though is has the corresponding solder pads on the PCB. When I look in System Profiler, there's no 3rd empty SATA port shown (unlike in this guide, which applies for newer models).
Thus is seems there's missing more than a connector and two resistors to get a 3rd port. On the other hand i'm feeling challenged to dig deeper ever since i disassembled my iMac in order to realize I'm missing the port.
Does anyone knows more about this?
While you might be able to connect another SATA device internally you still need some where to mount the device.
You risk interfering with the systems airflow causing the fan to kick in more often, besides the risk of causing something to short on the devices housing. And lastly, you void your warrantee or even a parts exchange (via Apple) if your logic bd. dies.
What are you planning to install? That you can't do externally? With a lot less hassle or risk. Just the fact you can doesn't make it smart to do.
Any news about the possible upgrade?
I have also been very interested about enabling the 3rd port ever since I tried to install additional SSD drive only to find the port missing.
