| USB B | When USB 3.0 came along, they came up with new type of USB B. And, this is used for SATA External drives. |

Molex
Molex connector is the vernacular term for a two-piece pin and socket interconnection. Pioneered by Molex Connector Company, the two-piece design became an early electronic standard. Molex developed and patented the first examples of this connector style in the late 1950s and early 1960s.
