What is USB 3.1 and when it was released
USB Technology develops fast as the modern technology is blooming in data transmitting. We have already known well about USB 3.0. USB 3.0 is widely used for data transfer among popular devices, such as PCs, tablets, hybrids, and mobile phones.USB 3.0 was first announced by USB Promoter Group in 2008. The new standard offers 10 times of the data transfer speed vs. USB 2.0 and is high efficiency that is 5.0Gbps.
When is the USB 3.1 release date?
The USB 3.1 is released on Dec. 23th, 2013 by USB 3.0 Promoter Group, which is the highest level of USB standards until now with the fastest data transfer speed.
Why do we need faster data transfer speed?
This picture from Kingston.com can interpret our needs for data transferring clearly.
Faster USB 3.1 Specification
USB 3.1 has a 10gbps speed. And deliver twice the effective data performance than USB 3.0. It is fully compatible backward with USB cables and connectors.
The specification is as the following:
• Delivers 10 Gbps USB data rate
* 2x improvement over current USB3.0 5 Gbps data rate
• Improved data encoding for more efficient data transfer leading to higher through-put and improved I/O power efficiency
• Compatible with existing USB 3.0 software stacks and device protocols
• Works with both existing 5 Gbps USB 3.0 hubs and devices, as well as USB 2.0 products
In common words, USB 3.1 is faster and more powerful than before, but it also consumes more power. With its release, the new Type-C 3.1 as a new cable and connectors is also introduced.
There are three connector of interfaces for USB 3.0(Superspeed+), Type-A(standard-A), Type-B(Micro-B) and Type-C.
TypeA and type C USB 3.1 Port
Type B of USB 3.1 Port
Type-A(standard-A) is the most widely used interface for connecting. Micro-B is mainly used in Smartphone and tablets. And the newly introduced Type-C 3.1 is used for lighter and thinner, and slimmer devices.

Supply better power Charge
USB 3.0 Promoter Group has said that the USB 3.1 connector and port are designed to accommodate future updates, making them future-proof.
Also, the Type-C 3.1cable can charge your tablets, smartphones and other devices faster with its up to 100 watts.
The test by Asus of USB 3.1
According to the technology reports from Asus Z97A usb 3.1, when the speed testing software continuously reading and writing, the reading speed comes up to 781.2MB/S, and the writing speed 797.8MB/S. The same environment of USB 3.0 test result is separately 446.5 MB/S and 448.6 MB/S. We can see the efficiency of USB 3.1 clearly.
The Competition from Intel
The only rival is Intel’s Thunderbolt technology, which is found primarily in Apple’s laptops and desktops. While as to the cost, USB have great advantage. Acer, as one of the world’s largest computer manufacturers, announced that it would favor USB 3.1 over Thunderbolt in all future devices.
Pamper Imagination of the Future.
Look forward to more USB 3.1 devices blooming in our daily life. The usb 3.1 is the most powerful USB interface with type-c. There will be more and more devices like computers, tablets, and computer calculating interface to apply the USB 3.1 interface. And the future advanced devices with the most efficient USB port will supply us faster speed for data transferring. We will have better experience in multimedia data applications. Let’s wait for more USB 3.1 devices.
