This is a good time to install one or two M.2 SSD drives to accelerate the performance of the QNAP.

Ensure the M.2 SSD drives are compatible with the QNAP using the QNAP SSD compatibility site

There are two M.2 slots towards the bottom of the motherboard.

Install the #2 drive first as it is under the side rail of the case.

The second slot is slightly hidden by the bottom rail of the case but still accessible.

Install the SSD Drive slot (1).

If you are only installing a single drive use this slot.
