Introduction To USB 3.1

USB 3.1 Gen2 is the latest USB specification, which was initiated by companies such as Intel. The data transfer speed can be increased to a speed of 10Gbps. Compared with USB 3.0 (ie USB3.1 Gen1) technology, the new USB technology uses a more efficient data encoding system and provides more than double the effective data throughput. It is fully backward compatible with existing USB connectors and cables.

Here are Selore&S-Global USB-C Docking Station 7-in-1 which have 3 USB 3.0 ports: 


❤️ This dual monitor display docking station convert your usb c port into 7 ports:2 HDMI, 3*USB 3.1 and 1* USB 2.0 ,100w pd.
❤️ 10Gbps USB 3.1,Fast speed transfer: 3*USB 3.1 up to 10G, backwards compatible with USB 3.0 / 2.0; 1*USB 2.0 ports are more suitable for mouse, keyboards or other slow device to improve work efficiency and avoid radio signal interference; The dual hdmi docking station supports Power Delivery, thunderbolt 3.0 technology with a rated power of 100W and offers significantly faster charging times.
❤️ For HDMI Fuction: Please ensure the Laptop has thunderbolt 3 / USB-C 3.1 Gen 2 /USB-C 3.1 Gen 1 port before purchase.


Features of USB 3.0

1. The read and write speed is as fast as flying under the ultra-high theoretical bandwidth.
In theory, the bandwidth of the USB3.1 port is 10Gpbs. Of course, the actual speed is definitely far from the theoretical value, but this also prevents us from reaching the ultra-high read and write speed of 800M/s in the actual test.
2. Ultra-thin interface.
The size of the old-fashioned USB port is 1.4 cm long and 0.65 cm wide. Obviously, it can no longer meet the increasingly urgent ultra-thin needs of portable electronic devices, especially mobile phone manufacturers. The size of USB3.1 Type-C is 0.83 cm long and 0.26 cm wide. Lightweight is a step up. After the mobile phone interface has been upgraded from the original Mini USB to Micro USB, it has become the standard configuration of all smartphones, and indirectly promoted the first wave of ultra-thin smartphones, and then to today's ultra-thin USB3.1 Type -C, it is not difficult to imagine that in the near future, a new wave of portable electronic devices will set off a wave of "there is no thinnest, only a thinner wave".
3. Double-sided plugging and unplugging significantly improves the user experience.
A very big advantage brought by USB3.1Type-C this time is that the design of double-sided plugging and unplugging has greatly improved the poor experience of USB data cables. I believe that many Android users will start to sigh, and finally they can charge their mobile phones with their eyes closed.
4. Super compatible old equipment will not be eliminated soon.
We know that USB compatibility has always been good, and the USB3.1 specification this time has inherited this very well. With only one adapter cable, USB3.1 can be easily compatible with USB3.0 and USB2.0 devices. However, in order to ensure the experience, the author still recommends that you upgrade your devices such as USB2.0 U disks and mobile hard disks that have been used for five or six years or even ten years.
5. The improvement of current output capability brings fast charging experience.
According to the USB3.1 specification, the interface can provide a maximum power supply capacity of 5V 20A or 100W. However, due to safety and device compatibility considerations, ASUS and other first-tier motherboard manufacturers have not completely released the power supply capability. Asus B85M- Take the G PLUS motherboard as an example, the current open power supply is 5V 3A, although it seems that only 15W is not high. But you must know that the power supply current of standard USB3.0 is only 1A. For devices that support high-speed charging, the current of 3A is undoubtedly a great boon, and it is very refreshing to think about three times the charging speed.


What are the improvements of USB3.1 compared with USB3.0?

📍 The USB3.1 standard was released in July 2013, and the maximum theoretical bandwidth has doubled compared to that of USB3.0, reaching 10Gb/s (Super Speed). The encoding method of USB3.1 has been changed from 8b/10b of USB3.0 to 128b/132b, and the bandwidth loss rate has dropped from 20% to about 3%. After conversion, the bandwidth also exceeds 1.2GB/s, which also means that in The limit transfer rate of USB3.1 in real use is expected to be close to 1GB/s.
📍USB3.1 and USB3.0 transfer speed comparison
Although there is still no native USB3.1 support, compared to native USB3.0, the highest access speed of third-party USB3.1 solutions is still more than 60% higher than native USB3.0, and the overall performance does not We are disappointed.
📍The emergence of USB3.1 Type-C interface will play a very important role in mobile devices. From the current point of view, Type-C in USB3.1 is most likely to become the connection standard in the future, providing data transmission, peripheral connection , display output and other integrated connection solutions.
