Hi,
I don't think the SSD you have is actually Mini PCIe, but instead mSATA.
They use the same connector, and have some electrical compatibility, but the routing need to go to a SATA controller instead of the PCIe bus on the host board.

I think there are Mini PCIe SSD's out there, but they are rare, and probably a bit expensive.
