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.
