Why does the USB cable included with the 2.5″ portable drives have two USB connections on one end?
The USB cable included with the 2.5″ portable drives has two USB Type A connectors; a main connector and a secondary connector. The main connector connects to a computer’s USB port to receive both power and data from this single connection. The secondary connector connects to a second USB port and allows for the drive to receive additional power from this port. This ensures that the drive receives adequate power to operate correctly.
