USB 3.0 Devices & Applications

  Updated in November 2011

What new applications does USB 3.0 enable?
In a nutshell, any high-bandwidth device that works with USB 2.0 will become better if updated with USB 3.0 support. At the moment, devices that tax the throughput of USB 2.0 include:

  • External hard drives - capable of more than twice the throughput available from USB 2.0, not to mention bus-powered portable drives that require non-compliant Y-cables to get the current they require for reliable operation
  • Full HD video capture solutions
  • High resolution webcams, surveillance cameras
  • Video display solutions - e.g. DisplayLink USB video technology
  • Camcorders
  • Digital still cameras
  • Multi-channel audio interfaces
  • External optical media - i.e. Blu-Ray drives
High end flash drives can also push USB 2.0 pretty hard, and oftentimes if multiple devices are connected via hub, throughput will suffer.

USB 3.0 opens up the laneways and provides more headroom for devices to deliver a better overall user experience. Where USB video was barely tolerable previously (both from a maximum resolution, latency, and video compression perspective), it's easy to imagine that with 5-10 times the bandwidth available, USB video solutions should work that much better. Single-link DVI requires almost 2Gbps throughput. Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will find its way into some products that previously weren't USB territory, like external RAID storage systems.


Where are those SuperSpeed USB 3.0 products?
USB 3.0 silicon such as USB host controllers, peripheral chipsets and hubs compliant with the SuperSpeed bus have arrived in the latter half of 2009. Since then, a handful of portable hard drives, flash drives, drive docks, Blu-ray optical drives, hubs and upgrade cards have begun appearing on retail shelves. DisplayLink also revealed plans to ship USB 3.0-compliant USB video silicons by Q4 2010.

Here's a list of commercially available SuperSpeed USB products:











And this is a list of SuperSpeed USB products confirmed in development. They are either planned or concepts.
