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.

why we need that speed of USB

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

TypeA and type C USB 3.1 Port

Type B of 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.

The 2013 CES is held from Jan 8th, 2013 to Jan 11th 2013. The USB 3.0 Promoter Group announced to the Media that they will add a much higher data rate and much larger Capabilities.

The data transfer speed will doubles and the new USB 3.0 will be fully backward compatible with USB 2.0 and USB connectors and USB cables. It is said that the specification will be released in the middle of this year.

Let’s have a overview of the USB 3.0 hightlights.

  • New 10 Gbps USB data rate
  • Compatibility with existing cables and connectors
  • 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 class protocols
  • Compatible with both existing 5 Gbps and new 10 Gbps USB 3.0 hubs and devices, as well as USB 2.0 products

The USB 3.0 is called SuperSpeed USB. The Chairman of the USB group hopes to best improve user experience and connectivity performance. The SuperSpeed USB will be more efficient for the more emerging USB applications and hardware.

Let us expect the 10 Gbps USB. And we will embrace the convenience that it brings to us.

Not to be Outdone, Asus Struts its SuperSpeed USB Stuff

On the heels of the notice of Gigabyte’s mega-volume announcement, Asus has shot back with its own pedigree and the breadth of their commitment to innovation. The company has definitely been a major player in the adoption of new technologies and new form factors. Gigabyte may hold the title of most, but Asus asserts, and we agree, they have always been first. First motherboard with USB 3.0 certification from the USB-IF, first nettop with USB 3.0, first to integrate USB 3.0 into their full range of products, not a long list, but definitely an impressive reminder of how hard they have been working to make the best product possible.
Asus has always had our loyalty since the early days of consumer PCs. We’ve gladly ordered products that were the first and best in: tweaked motherboards, Dual CPU capability, SLI support, integrated IO systems, small form factor machines, the EEE PC. That list goes on quite a bit longer and reads like a greatest-hits list of personal computing. We expect sharks with lasers to be built in to their next system at this rate. If you have a few days, try a search for Asus on our site, and you can see for yourself how often we find them newsworthy. One thing is for sure, “new” and “hotness” are words that will be associated with Asus for a long time to come.

World’s First USB 3.0 Host Controller has born!
Wednesday, June 03rd, 2009 | Author: Grace

resize1Imagine uploading an entire HD movie to your laptop in just over a minute. Imagine downloading all the 100-plus MP3 files of an audiobook to your player in seconds. How about getting the latest video from your camcorder to your desktop ready to mash up almost instantaneously, so you can beat your buddies onto YouTube? Sounds great, right?

That’s what the developers of the next-generation Universal Serial Bus technology are counting on when they release the spec for USB 3.0—also known as SuperSpeed USB.

Manufacturers are already gearing up for SuperSpeed USB with NEC being the first to announce the first USB 3.0 host controller, which is about one of the few silicon products that will guarantee instant success in this economy. NEC Electronics expects external hard drives, SSDs, flash drives and of course the computers themselves will be the first to receive the SuperSpeed USB upgrade.

A demo by Seagate at CES 2009 has already shown that even a prototype can reach upwards of 165MB/s which in perspective is almost 5 times faster than the fastest USB hard drive or flash drive. If USB 2.0 chip optimization history is any indication, we are looking at USB 3.0 hitting top speed in two years. Designated µPD720200, the world’s first xHCI-compliant host silicon will also be backward compatible with USB 1.1 and USB 2.0. Samples of the chips will become available in June 2009 at $15 USD, along with free Windows drivers. NEC anticipates monthly production to reach one million units by September of this year, and rapid adoption in second half of 2010.

New time of  USB is coming!
