USB 3.0 -- also known as SuperSpeedUSB -- provides a standardized interface for a wide variety of devices that are connected to a PC or audio/high-frequency device. It's just a hardware device, and USB3.0-related features can only be utilized when a USB3.0-related hardware device is installed within the computer! Devices ranging from keyboards to high-throughput disk drives are able to use this low-cost interface for a smooth-running plug-and-play connection, with basically no effort on the part of the user. While maintaining compatibility with USB 2.0, the new USB 3.0 offers several enhancements as follows.

● Greatly increased bandwidth - up to 5Gbps full-duplex (480Mbps half-duplex for USB 2.0).

● Enables better power management.

● Enables the host to provide more power to the device, enabling applications such as USB - rechargeable batteries, LED lighting and mini fans.

● Enables the host to recognize devices faster.

● The new protocol enables more efficient data processing.
