Hello Friends, i have just over a conversation with friend on USB 3.0, and i think i should share the main points of this conversation with you also.. :)

What is USB 3.0?
USB 3.0, also known as SuperSpeed™ USB, is the latest generation of USB (Universal Serial Bus)
technology, which has standardized peripheral connectivity since 1996. It operates at speeds up
to 5 Gbps.

How fast is USB 3.0 compared to USB 2.0 and other technologies?

USB 3.0 is 10x faster than USB 2.0 technology. It is 67% faster than eSATA and 25x faster than
standard WiFi.

What are the main benefits of USB 3.0 compared to USB 2.0?
USB 3.0 offers 3 major benefits over USB 2.0:
1. USB 3.0 transfers data ten times faster, resulting in greater productivity and user
satisfaction.
2. USB 3.0 has improved power efficiency, which delivers longer battery life for laptops,
tablets and peripherals connected via USB 3.0.
3. USB 3.0 has increased power output, which lets users power and charge more devices,
more quickly, without the need for an external power source.

What are the major technical changes that enable these benefits?
The increased data throughput speed is achieved through the addition of two wires to the bus,
enabling bi-directional data transfer and the ability to read and write data simultaneously.
Additionally, a new interrupt-based data signaling method replaces device polling for a further
boost in speed.
This interrupt-based data signaling also eliminates the power drain associated with USB 2.0,
delivering enhanced power efficiency and a preservation of battery life for laptops, tablets and
virtually any peripheral connected via USB 3.0. Legacy 2.0 devices also benefit from this feature,
which is backward compatible with USB 2.0 devices.

Will current USB 2.0 products work with the new USB 3.0 ports?
Yes, the ports are compatible; however, the devices will connect at the lower USB 2.0 speed of
480 Mbps.

Is USB 3.0 available in laptops today?
Yes, most major brands of laptop

How do I know which ports on a laptop are USB 3.0?
USB 3.0 ports are usually highlighted by a blue plastic tab and/or a Super Speed logo.

Are there other market trends driving the adoption of USB 3.0 and the need
for USB 3.0 products?
Yes. There are 4 major trends driving the need for USB 3.0:
1. The reliance on virtual workforces and shared workspaces (also known as “Hot Desking”
or “Hoteling”) is increasing. Products such as USB 3.0 docking stations and hubs increase
the speed and efficiency of these practices.
2. Enterprises are more frequently supporting two or more laptop standards. In addition,
the increase in the “Bring-Your-Own-PC” (BYOPC) trend allows users to choose their
own laptop. In these scenarios, enterprise efficiency calls for USB 3.0 docking stations,
universal charging and USB 3.0 hubs for quick connectivity of peripherals and enhanced
productivity.
3. The emergence of Ultrabooks in 2012 means a growing number of systems with limited
ports, no optical drive and no available OEM docking stations. USB 3.0 peripheral devices,
docking stations and hubs efficiently bridge this gap, while offering the benefits of
enhanced speed and power output.
4. Many IT organizations face a mandate to lower TCO and improve productivity. USB 3.0
products address this demand with SuperSpeed data and video transfer rates 10x faster
than current USB 2.0 technology. Additionally, USB 3.0 video adapters add one or two
monitors for increased worker productivity of up to 50%.

What peripheral products are available today using USB 3.0?
Most major brands of flash (thumb) drives, hard drives and USB hubs offer USB 3.0 products to take
advantage of the fast data transfer. Additional available products include USB 3.0 docking stations
and video adapters.
