USB 3.0 is Arriving

Intel demonstrated a Consumer Electronics Show in (CES) in Las Vegas, the USB 3.0 version of the work last week. This is why it will eSATA and FireWire out of date.

When the usb 3.0 sata hdd dock is expected to market in early 2010, will be 10 years now ubiquitous USB 2.0 release (April 2000). The current USB 2.0 specification running on the theoretical maximum speed of 480Mbps, and can provide power.

According to USB Implementers Forum, a two billion of the USB 2.0 devices shipped in 2006 (every three people in the world I) and install the appropriate 6 million (almost everyone in the world one). November 2007, USB Implementers Forum announced USB 3.0 specification, an official at the CES 2009 Intel demonstrated the technology.

Now, the juice: USB 3.0 5Gbps commitment to the theory of maximum rate, which means it's 10 times faster than USB 2.0. USB 3.0 is also full duplex, which means it can simultaneously upload and download (it is bi-directional), USB 2.0 is the only half-duplex.

With the eSATA and FireWire 800, USB 3.0 is far side of the square made superior. One eSATA, the external connections, as an internal SATA 1.0 bus running the same speed, with the highest 3Gbps theory. This makes it faster than eSATA USB 3.0 and six times faster than FireWire 800 (in 800Mbps full duplex).

The USB 3.0 also provides another advantage, eSATA is faster than FireWire 800, FireWire it can not supply. There is USB 3.0 faster than the speed advantage, even in the power supply.

Finally, USB 3.0 has a good power management, which means the device can enter the idle, pause, and sleep state. This may mean more laptop batteries and other battery-based support for USB devices such as cameras and mobile phones life.

Of course, there are other factors to consider; 3200 FireWire standard is in the works and promised to allow the existing FireWire 800 hardware, the speed of 3.2GHz. USB 2.0, is generally not consistent with its theoretical maximum throughput, because of its hardware and software configurations, which are more closely dependent on FireWire.

It's hard to say whether the USB 3.0 architecture will still be updated to use more CPU time than the same line of fire.

However, powerful hardware age (who can say "3.2GHz quad-core processor"?), Which means that all of the FireWire USB 3.0 still does not match the theoretical maximum of 5Gbps's.

The final signal that this war has been won, Apple's recent decision to favor it from the USB cable in the consumer channel FireWire. Previously, Apple was firing one of the greatest advocates. And affirmed the company will become one of the first to adopt USB 3.0.

In short, we can not wait for vendors like Gigabyte and Asus motherboards began to support the technology and mainstream PC makers such as Dell, started into their products. Of speed.
