Seen the SUPERSPEED USB logo brandishing around and wondered what it meant?

Superspeed USB 3.0 (USB meaning Universal Serial Bus) is the third major revision of the USB standard for computer connectivity.  During the late 1990’s the first major revision was made to what was then known as the USB1.1 specification, by adding a new transfer speed (previously Low Speed of 1.5Mbit/s to High Speed of 480Mbit/s) thus creating today’s USB 2.0.  Well similarly a further revision occurred, whereby the following improvements were made and the USB 3.0 was born:

  • Added a new transfer type, known as Super Speed
  • More bandwidth: USB 3.0 unlike its predecessors uses two unidirectional data paths (one to receive data one to transmit)
  • Improved bus utilisation
  • Support to rotating media

In a nutshell this all means that the USB 3.0 has transmission speeds of up to 3.5 GB/min, 10 times faster than USB 2.0.  The user experiences a significantly quicker data transmission, less power consumption and is also backwards compatible with the USB 2.0.  Supply of USB 3.0 remains quite limited in comparison with the ever available USB 2.  However with Handisc’s customers needing greater speed and capacity, we are up to date!  Not only are we able to supply USB 3.0 Keys, but also provide IMI’s Super speed USB 3.0 Key / Hard Drive duplicator, the IMI M5300.
