Interfacing with SATA?

At the moment I need to have the SATA cable connected to the Arduino so that I can log the data being sent over the SATA cable.
After analyzing that and checking out the parts that I need, I need to have the Arduino read what's being sent, and depending on what's sent, it needs to output back a string.

For example:
The host (SATA) sends a string asking what, for example, DVD is in a drive. The Arduino needs to read this string, and send back that it's a certain DVD.

I found this:

and a supplier for it, but I have yet to find a pinout or even a picture of it to know what I'm dealing with or if it will even work.

If I can convert the SATA signal to USB, it'll slow the transfer rate significantly enough that I can interface with it.

Would I be able to go SATA -> USB -> Serial and interface with it over the Arduino Serial interface?
