A:Answer I just bought mine tonight and already took it apart. It has a 128gb m.2 pcie SSD. If you end up taking your back cover off exposing the board, you'll see a metal plate (lift to remove) to the left of the heat sink. Under there you will find the RAM and M.2 SSD. There is a spot on the bottom of the board for a 2.5 SSD, but there is no cable. For future reference you'll need part # L20103-001, if you want to add a secondary 2.5" drive.
