USB 3.0 전송 속도를 10Gbps로 확장

컴퓨팅 생활중 재미있는건중 하나는 기술의 진보와 발전을 보는것일 텐데요.

USB 3.0 기술의 발전에 대한 내용이 있어 소개 드립니다.

내용에 앞서 간단하게 정리하자면 

확장된 규격으로 나올 칩셋과 제품들만  10Gbps 속도를 낸다는것

USB 2.0 기술처럼 full speed usb 3.0, high speed usb 3.1 네이밍을 가지지 않을지 :)

 USB 규격의 표준화 단체 "USB Implementers Forum (USB-IF)"는 USB 3.0 (SuperSpeed​​ USB)의 표준 확장을 하고, 전송 속도를 10Gbps로 향상시킬 예정이라고 발표 했다.

 

 현재 5Gbps인 USB 3.0의 최대 전송 속도를 2 배인 10Gbps. 또한, 데이터 암호화의 개량으로 보다 효율적인 전송을 행하는것 외, 커넥터 나 프로토콜 등은 기존의 USB 3.0 및 USB 2.0과 호환된다.

 

2013 년 1 분기에 업계에서 연구 / 검토를 하고, 2013 년 중반에는 규격 책정을 완료 할 전망이다.

 

  USB 3.0은 2008 년 11 월에 책정 되었으며, 전송 속도 5Gbps는 이전 버전의 USB 2.0의 약 10 배에 해당 되지만,  미국 Apple은 2011 년 2월 최대 전송 속도 10Gbps의 "Thunderbolt"을 발표 했다.

 

USB-IF에 따르면 현재 시장에는 710 개 이상의 USB 3.0 지원 제품이 존재 한다고 한다.

SuperSpeed USB (USB 3.0) Performance to Double with New Capabilities 

USB 3.0 Promoter Group to Increase Data Through-put Performance of USB 3.0 to 10 Gbps 

LAS VEGAS – January 6, 2013 – The USB 3.0 Promoter Group today announced 

development of a SuperSpeed USB (USB 3.0) enhancement that will add a much higher 

data rate, delivering up to twice the data through-put performance of existing SuperSpeed 

USB over enhanced, fully backward compatible USB connectors and cables. This supplement 

to the USB 3.0 specification is anticipated to be completed by the middle of this year. 

Key characteristics of the higher-rate SuperSpeed USB solution include: 

• New 10 Gbps USB data rate 

• Compatibility with existing cables and connectors 

• Improved data encoding for more efficient data transfer leading to higher throughput 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 

“With USB technology continuing to be the data and power delivery path of choice across 

personal computing and consumer electronics, we are always looking ahead to how to best 

improve user experience and connectivity performance,” said Brad Saunders, USB 3.0 

Promoter Group Chairman. “Doubling SuperSpeed USB performance will be especially 

beneficial for emerging USB docking and storage applications.” 

“For our customers, 10Gbps USB represents an important evolution in this ubiquitous I/O 

standard,” said Mark VandenBrink, Vice President and Chief Technology Officer, PC Global 

Business Unit, HP.  “By doubling the bandwidth while maintaining full backwards 

compatibility with the broad ecosystem of USB peripherals and software, we will be able to 

better meet the needs of our customers with this high-speed technology.” 

“We recognize that more mainstream client computing applications are going to need higher 

through-put to user-connected peripherals and devices,” said Alex Peleg, Vice President, 

Intel Architecture Group. “Intel is fully committed to delivering 10Gbps USB performance to 

these platforms while retaining compatibility with the existing USB ecosystem to help to 

satisfy user demand for low-cost, higher-performance solutions.” 

“Microsoft has been a strong supporter of the USB community where we have advocated 

balancing innovation and compatibility. The planned updates to USB 3.0 are consistent with 

our views," said Dennis Flanagan, General Manager, Windows Ecosystem Engagement.  

"These updates will enable higher data rates and allow combining of disk, high-definition 

audio/video and networking traffic on a single cable — all while maintaining compatibility 

with billions of existing devices.”
