The M.2 connectors on the motherboard support only M.2 PCIe SSDs.
Follow the steps below to correctly install an M.2 SSD in the M.2 connector.
Step 1:
Locate the proper mounting hole based on the length of your M.2 SSD drive. If needed, move the standoff
to the desired mounting hole. Insert the M.2 SSD into the M.2 connector at an angle.
Step 2:
Press the M.2 SSD down and then use the included screw to secure it in the connector.
* Types of M.2 SSDs supported by each M.2 connector:
M.2 PCIe x4 SSD M.2 PCIe x2 SSD M.2 SATA SSD
