Use a Phillips #00 screwdriver to remove the 6 mm screw.

Use tweezers or an iFixit opening tool to lift the SSD up and away from the thermal pad it rests on.

Grip the SSD between your fingers and pull it horizontally to the right at a slight angle until it releases from the port.

The thermal pad is slightly sticky, and may stick to the bottom of the SSD as you remove it. If it does, be careful not to damage it, and make sure to reinstall the thermal pad before replacing the SSD.
