These connectors are SATA 6Gb/s interface ports. Each connector can connect to one

Important
∙ Please do not fold the SATA cable at a 90-degree angle. Data loss may result during
transmission otherwise.
∙ SATA cables have identical plugs on either sides of the cable. However, it is
recommended that the flat connector be connected to the motherboard for space
saving purposes.
