Both mSATA and mini PCIe share the same form factor and similar electrical
pinout assignments on their connectors. There was no clear mechanism to
distinguish if a mSATA drive or a Mini PCIe device is plugged into the socket until
recently that SATA I/O issued an ECN change (ECN #045) to redefine pin-43 on
mSATA connector as “no connect” instead of “return current path” (or GND).
When a mSATA drive is inserted, its pin-43 is “no connect”, and the respective pin
on the socket is being pulled-up to logic 1. When a mini PCIe device is inserted,
its pin-43 forces the respective pin on the socket to ground, or logic 0.
The pin assignments of MPCIE1, MPCIE2 are listed in the following table:
