Applications
USB 3.0/USB 3.1 Gen 1 opens up the laneways and provides more headroom for devices to deliver a better overall experience. Where USB
video was barely tolerable previously (both from a maximum resolution, latency, and video compression perspective), it's easy to imagine
that with 5-10 times the bandwidth available, USB video solutions should work that much better. Single-link DVI requires almost 2Gbps
throughput. Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will find its way
into some products that previously weren't USB territory, like external RAID storage systems.
Listed below are some of the available SuperSpeed USB 3.0/USB 3.1 Gen 1 products:
• External Desktop USB 3.0/USB 3.1 Gen 1 Hard Drives
• Portable USB 3.0/USB 3.1 Gen 1 Hard Drives
• USB 3.0/USB 3.1 Gen 1 Drive Docks & Adapters
• USB 3.0/USB 3.1 Gen 1 Flash Drives & Readers
• USB 3.0/USB 3.1 Gen 1 Solid-state Drives
• USB 3.0/USB 3.1 Gen 1 RAIDs
• Optical Media Drives
• Multimedia Devices
• Networking
• USB 3.0/USB 3.1 Gen 1 Adapter Cards & Hubs
Compatibility
The good news is that USB 3.0/USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all,
while USB 3.0/USB 3.1 Gen 1 specifies new physical connections and thus new cables to take advantage of the higher speed capability of
the new protocol, the connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as
before. Five new connections to carry receive and transmitted data independently are present on USB 3.0/USB 3.1 Gen 1 cables and only
come into contact when connected to a proper SuperSpeed USB connection.
Windows 10 will be bringing native support for USB 3.1 Gen 1 controllers. This is in contrast to previous versions of Windows, which
continue to require separate drivers for USB 3.0/USB 3.1 Gen 1 controllers.
USB Type-C
USB Type-C 是一種小巧的新型實體連接器。連接器本身可以支援多種新穎的 USB 標準,例如 USB 3.1 和 USB Power Delivery (USB
PD)。
替代模式
USB Type-C 是極為精巧的新型連接器標準。其大小約為舊型 USB Type-A 接頭的三分之一。每種裝置應該都能使用此單一連接器標
準。USB Type-C 連接埠可支援各種使用「替代模式」的通訊協定,可讓您使用能自該單一 USB 連接埠輸出 HDMI、VGA、DisplayPort
或其他類型連線的配接器。
USB Power Delivery
USB PD 規格也與 USB Type-C 有著密不可分的關係。目前智慧型手機、平板電腦及其他行動裝置通常都會使用 USB 連線來充電。
USB 2.0 連線能提供最高 2.5 W 的電力,可用來為手機充電,但也僅止於此。舉例來說,為筆記型電腦充電的電力可能就需要高達
60 W。USB Power Delivery 規格可將傳輸的電力提高到 100 W,並且為雙向傳輸,所以裝置可以接收電力輸入,也可以向外傳輸電
力。而且在傳輸電力時,裝置還可以透過該連線來傳送資料。
這也代表筆記型電腦專用的充電線即將走入歷史,因為只要有了標準 USB 連線,就能為所有的裝置充電。從現在開始,您不但可以
使用行動電源為智慧型手機和其他可攜式裝置充電,還可以用來為筆記型電腦充電。您可以將筆記型電腦接上一台連接電源線的外
部顯示器,這台外部顯示器就會在您將它用作外接式螢幕的同時,為您的筆記型電腦充電;這麼方便的使用方式,只需要一條小小
的 USB Type-C 線即可辦到。若要享有 USB Type-C 線所帶來的好處,只擁有 USB Type-C 連線還不夠,裝置和纜線都必須支援 USB
Power Delivery 才可以。
USB Type-C 和 USB 3.1
USB 3.1 是全新的 USB 標準。USB 3 的理論頻寬為 5 Gbps,而 USB 3.1 的理論頻寬則為 10 Gbps。後者的頻寬是前者的兩倍,速度就
和第一代 Thunderbolt 連接器一樣快。USB Type-C 和 USB 3.1 不可混為一談。USB Type-C 只是一種連接器型態,其中所使用的技術
