What is the difference between USB3.1 and USB3.0?

From  the test results, USB 3.1 interface, the actual performance of a lot  higher than the USB 3.0, continuous reading and writing speed of 500MB /  s to 600MB / s or so, the highest score can even break 700MB / s. The USB 3.0 interface, the continuous read and write rate of about 300MB / s to 400MB / s or so.
 
Although USB3.1 nominal interface theoretical rate is 10Gbps, but it  also retains part of the bandwidth to support other functions, so the  actual effective bandwidth of about 7.2Gbps, the theoretical  transmission speed should be up to
 
To 900MB / s, so that the USB 3.1 interface is still a lot of room for  improvement, at least should reach the level of 800MB / s.
 
About  USB3.1 is now the focus of discussion, USB3.1 is the latest USB  specification, the specification by Intel and other large companies  initiated. Data transfer speeds up to 10Gbps. Compared  with USB 3.0 technology, the new USB technology uses a more efficient  data encoding system, and provides more than twice the effective data  throughput. It is completely backward compatible with existing USB connectors and cables. ,  And related USB3.1 products have also gradually into the people's  attention, which in particular that the traditional host-side equipment  to provide extended interface motherboard is the most active. Although  Intel to the next generation of 100 series chipset still does not  provide native USB3.1 support, but as before USB3.0, before the original  program has been, are integrated third-party master chip to provide new  interface The From  the test results, USB 3.1 interface, the actual performance of a lot  higher than the USB 3.0, continuous reading and writing speed of 500MB /  s to 600MB / s or so, the highest score can even break 700MB / s.

TheUSB3.1  standard released in July 2013, the maximum theoretical bandwidth  compared to USB3.0 doubled to 10Gb / s (Super Speed +). USB3.1  encoding from the previous USB3.0 8b / 10b replaced by 128b / 132b,  bandwidth loss rate dropped significantly from 20% to 3%, after  conversion, the bandwidth is also more than 1.2GB / s, which also means  that The actual use of USB3.1 limit transmission rate is expected to close to 1GB / s.
 
Although  the same upgrade as the past, USB3.1 also brought a higher transmission  rate, and repair the previous problems in all aspects, but people are  talking about more with USB3.1 introduced a new Type-C interface. Similar to Apple's Lightning interface, Type-C interface to cancel the  foolproof protection design, so regardless of positive and negative can  be inserted into the normal use, eliminating the need to identify the  direction of the insertion of the trouble.
 
USB3.1 Type-C another big selling point is the ability to enhance the ability to charge mobile devices. USB 3.1 interface under the maximum allowable power supply standards  increased to 20V / 5A (Type-A / B only), can provide up to 100W power  output capacity.
The  highest standard for Type-C is 12V / 3A, 36W charging capacity is  enough to use some thin notebook, which is New MacBook dare to give up  MagSafe and use Type-C as a charging interface, an important reason. Function  USB 3.1 Type-C also introduces a new Alternate Mode, which means that  Type-C interfaces and data lines can transmit non-USB data signals. Alt  Mode has been able to support DisplayPort 1.3 and MHL 3.2  specifications, and USB-IF is also seeking support for other functional  standards, in addition to the video interface, such as Ethernet and  other interfaces can also be Type-C support. USB3.1 and USB3.0 transmission speed comparison
At  present, although there is no native USB3.1 support, but compared to  the original USB3.0, third-party USB3.1 solution the highest access  speed or higher than the native USB 3.0 to 60% or more, the overall  performance did not make We are disappointed.
