The era of USB 3.0 aka SuperSpeed USB has started to begin as leading manufacturers are now producing motherboard & devices with support for latest USB 3.0 technology.

USB 3.0 or SuperSpeed

Features of USB 3.0 (SuperSpeed) -

  • Aims to Offer data transfer rate of 5GB/s which is 10x faster than Hi-Speed (USB 2.0)
  • Backward compatibility with USB 2.0 devices and computers.
  • Delivers 900 mA of power per USB port, an 80% increase over USB 2.0 which only provides 500mA.
  • New connectors and cables for higher speed data transfer.
  • Improved Power Efficiency. No device polling and lower active and idle power requirements.

Though, one can easily connect a USB 3.0 cable to a computer supporting USB 2.0 ports but the results won’t be pleasing, because the bandwidth would not be same as offered by USB 3.0. So, you must use a compatible board and device enhanced with USB 3.0 to get the best performance. However, there is a way to connect USB 3.0 devices to non-compatible motherboards having USB 2.0 by adding some small hardware.
