USB 3.0 - The new standard
Connectivity
USB is by far the most common connection for IT devices. It was originally developed in order to
simplify the wide range of connections to PCs and to enable installation of various accessories
such as mice, keyboards, webcams etc. USB has now become the standard connection for almost
all digital devices such as netbooks, notebooks, Smartphones and all-in-one PCs.
With the new "SuperSpeed" USB 3
.0 version, this connection has once again been considerably
improved. As USB 3.0 has been officially adopted as the global standard, perfect functionality
between the relevant devices is now ensured.
Essential features of USB 3.0:
1. Speed is the most important feature:
5GBit/s means a data transfer rate which is about 10x higher than with USB 2.0!
Users of external hard drives will notice a considerable d
ifference.
This is illustrated by a comparison between USB 3.0 and previous types of connection
In order to achieve the maximum transfer rate of 5 GBit/s, all components in the connection chain
(boards -> cables -> devices) must be certified for USB 3.0
Vivanco has the necessary range of accessories.
Thanks to optimisation of communication between devices (transfer protocol) even the connection
of U
SB 2.0 devices (e.g. USB memory sticks) to USB 3.0 ports can result in a speed increase of up
to 8%.
2. Compatibility:
USB 3.0 devices are compatible with USB 2.0 and USB 1.1, however they then only provide
the specified data transfer rates.
3. Energy efficiency:
USB 3.0 supports various power saving modes, which in particular increases the operating
times of battery-powered devices.
