Why does the USB cable included with 2.5″ portable drives have two USB connections on one end?
The USB y-cable included with our 2.5″ portable hard 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.
