USB features

The Universal Serial Bus, or well known as USB was introduced to the PC world in 1996 which dramatically simplied the connection

between host computer and peripheral devices such as mice and keyboards, external hard drive or optical devices, Bluetooth and many

more peripheral devices in the market.

Let's take a quick look on the USB evolution referencing to the table below.

Table 1. USB evolution

Type Data Transfer Rate Category Introduction Year

USB 3.0/USB 3.1 Gen 1 5 Gbps Super Speed 2010

USB 2.0 480 Mbps High Speed 2000

USB 1.1 12 Mbps Full Speed 1998

USB 1.0 1.5 Mbps Low Speed 1996

USB 3.0/USB 3.1 Gen 1 (SuperSpeed USB)

For years, the USB 2.0 has been rmly entrenched as the de facto interface standard in the PC world with about 6 billion devices sold, and

yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands. The USB 3.0/USB 3.1 Gen 1

44 Technology and components

nally has the answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.1 Gen 1

features are as follows:

• Higher transfer rates (up to 5 Gbps)

• Increased maximum bus power and increased device current draw to better accommodate power-hungry devices

• New power management features

• Full-duplex data transfers and support for new transfer types

• Backward USB 2.0 compatibility

• New connectors and cable

The topics below cover some of the most commonly asked questions regarding USB 3.0/USB 3.1 Gen 1.

Speed

Currently, there are 3 speed modes dened by the latest USB 3.0/USB 3.1 Gen 1 specication. They are Super-Speed, Hi-Speed and Full-

Speed. The new SuperSpeed mode has a transfer rate of 4.8Gbps. While the specication retains Hi-Speed, and Full-Speed USB mode,

commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to

maintain backward compatibility.

USB 3.0/USB 3.1 Gen 1 achieves the much higher performance by the technical changes below:

• An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below).

• USB 2.0 previously had four wires (power, ground, and a pair for dierential data); USB 3.0/USB 3.1 Gen 1 adds four more for two pairs

of dierential signals (receive and transmit) for a combined total of eight connections in the connectors and cabling.

• USB 3.0/USB 3.1 Gen 1 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-fold

increase in theoretical bandwidth.

With today's ever increasing demands placed on data transfers with high-denition video content, terabyte storage devices, high megapixel

count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the 480Mbps

theoretical maximum throughput, making data transfer at around 320Mbps (40MB/s) — the actual real-world maximum. Similarly, USB

3.0/USB 3.1 Gen 1 connections will never achieve 4.8Gbps. We will likely see a real-world maximum rate of 400MB/s with overheads. At this

speed, USB 3.0/USB 3.1 Gen 1 is a 10x improvement over USB 2.0.

Technology and components 45

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 nd 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 species 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 8/10 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.

Microsoft announced that Windows 7 would have USB 3.1 Gen 1 support, perhaps not on its immediate release, but in a subsequent Service

Pack or update. It is not out of the question to think that following a successful release of USB 3.0/USB 3.1 Gen 1 support in Windows 7,

SuperSpeed support would trickle down to Vista. Microsoft has conrmed this by stating that most of their partners share the opinion that

Vista should also support USB 3.0/USB 3.1 Gen 1.

Super-Speed support for Windows XP is unknown at this point. Given that XP is a seven-year-old operating system, the likelihood of this

happening is remote.
