Hello! Those two pins in the top of the board are the pins for terminal connection.

[jinarto]

Need to check it by yourself. Try both combinations. In Samsung Utility, should be a picture with correct PIN placement.

hi Mr. Roman,

Nothing will happend. If you will connect terminal wrongly - SSD will not detect terminal.
