With the development of computer technology in particular tekonlogi experiencing rapid growth, one of which is USB technology. Tekonolgi USB 3 is the latest USB connection technology will eventually replace the USB 2 technology. In this article we will discuss the slight difference with USB 2 USB 3 fundamental. Specifications
USB 3 is still using a concept not unlike USB 2.0, but there are a lot
of improvements and the use of a far-flung difference. The
concept that there is a USB to previous generations, but is still used
protocol and electrical interface used is not the same, as well as the
physical channel specification for USB 3.0 transfer traffic. Here are some differences USB 3 with USB 2 the main, are as follows:
Speed in data transferThere is a new technology in terms of data transfer, which is called the Super Speed abbreviated as the SS which reaches up to 5 Gbit / s (both electrical PCIe Gen2 more similar than USB 2.0). This speed is 6 to 10x faster than the maximum speed of USB 2.0.
Greater bandwidthNot just a mere unidirectional communication only, USB 3.0 has been used two orbits in the same direction, including: one for receiving data and another as the sender. So it can read and write data simultaneously (simultaneously). USB 2.0 and earlier do not support bi-directional technology is.
Power management is goodSet the power link connecting the U3 UO. Reduced power supply voltage from 4.4 V to 4V, then the flow is also enhanced (monjadi 150mA), so in addition to more 'energy efficient, a USB 3.0 port can be used 4-6 and increase the recharging device.
Bus utilization increases goodA new feature is added (using packet NRDY and Erdy) to give an indication on the host to be asynchronous, that is ready to use (no need to ask anymore).
Support for additional mediaThe addition of a new movie called StreamProtocol protocol, which allows a large number of logic flow in an Endpoint. As described earlier, the USB 3.0 has transmission speeds of up to 5 Gbit / s, which is 10 times faster than USB 2.0 (480 Mbit / s). Thus, USB 3.0 is faster in taking time for data transmission, power savings and still compatible with USB 2.0.
