Is a USB 2.0 cable able to provide USB 3.0 speeds when connecting two USB 3.0 devices?
No, a USB 2.0 cable cannot provide USB 3.0 speeds. The speed of a USB connection is determined by the slowest component in the chain. If you use a USB 2.0 cable to connect two USB 3.0 devices, the connection will operate at USB 2.0 speeds. USB 3.0 cables have additional wires and shielding to support the higher data transfer rates of USB 3.0.
To achieve USB 3.0 speeds, both the cable and the connected devices (including ports and controllers) must be USB 3.0 compatible. USB 3.0 is significantly faster than USB 2.0, offering higher data transfer rates, improved power delivery, and better overall performance.

Why does my external hard drive have 2 USB plugs?
It's important to note that not all external hard drives come with dual-head cables, and the necessity for such a cable depends on the specific power requirements of the hard drive and the capabilities of the USB ports on the computer or other devices. Always refer to the manufacturer's instructions and specifications to understand the power requirements and recommended cable usage for your external hard drive.
