M.2 Slot
The X11SDW-4C/14CN/16C-TP13F+ motherboard has four M.2 slots. M.2 was formerly
known as Next Generation Form Factor (NGFF). M.2 allows for a variety of card sizes,
increased functionality, and spatial efficiency. The M.2 slot at JMD1 supports PCI-E 3.0 x4
and SATA 3.0 interfaces in a 2280/22110 form factor, whereas the M.2 slot at JMD2 supports
PCI-E 3.0 x4, SATA 3.0, and USB 3.0 interfaces in a 3042 form factor. The M.2 slot at JMD3
supports PCI-E 3.0 x1.
