I have a Toshiba Portégé Z30-A. In the Motherboard (intel core i7 4th gen) i can see an Empty 5+28 pin Connector. i wonder it should be a PCIe express slot for SSDs. so any one of you please let me know what i thinking was correct and please tell me know what kind of PCIe slot is that and can i use this (https://www.newegg.com/global/in/Product/Product.aspx?item=N82E16820147691) in that slot.

Picture of the Slot available in my Drive

The specs on CNET says that laptop comes with a 128GB mSATA drive.

No idea why yours doesn't have it....but that could be what the socket is for.
