Solved! Unknown Empty Slot in my Mother Board

Oct 18, 2018
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 ( in that slot.

Picture of the Slot available in my Drive

please let me know if you have any quires
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.
