In the Know More About USB 3.0

Know More About USB 3.0 ImageSampai In the year 2009, or even now, USB 2.0 is still a standard interface that is a fact recognized by the world (with nearly 6 million devices that use this interface sold).

The speed of USB 2.0 reaches 480 Mbps, 320 Mbps in theory is, apparently not fast enough for us today.

USB 3.0 actually started to be introduced to the public in November 2008.

There are some new things which can be obtained via USB 3.0, among others:

Transfer rate reaches 4.8 Gbps bias.
Maximizing the power bus so that mamapu that support power-hungry devices.
New power management features.
Full - duplex data transfers, and support for a new type of transfer.
The new connectors and cables to support higher data transfers.

High-speed USB 3.0 obtained bias because it already has nine pairs of wire. Unlike the USB 2.0 which still has four pairs of wire. Besides the addition also occurs in the signaling method that digunakan.Meskipun still host-directed, but USB 3.0 is already using the model "asynchrounous", where USB 2.0 is still using "polling".

Here are other additional features that the bias obtained from the USB 3.0, among others:

More power if needed.
Streaming support for large number of transfer and for high speed.
Transfers can be entered into the low-power link between service intervals.

With the new USB 3.0 specification above, it definitely makes you want to upgrade your old USB feature. In the Know More About USB 3.0 Image

USB 3.0

Unlike the USB 2.0, USB 3.0 technology introduced since 2007. The advantages brought by the USB 3.0 when compared to USB 2.0 is the data transfer speed (transfer rate) that can reach 5 Gbit / sec. Wow, almost 10x USB 2.0 right? Another difference is the length of data cable problems. If the USB 2.0, you are advised manambah cable length with a maximum of 3 W to maintain accurate speed data transfer permanent. In USB 3.0, cable length is no longer a factor that affects the speed of data transfer. In addition, USB 2.0 requires a maximum power supply of 900 mA.

Know the Difference USB 2.0 with USB 3.0 Image

Another advantage compared with USB 3.0 USB 2.0 is its full duplex, meaning that the USB host can send and receive data continuously. As for the pin plug, USB 3.0 has a pin number 5 pieces.

USB 3.0 Weaknesses

One drawback of USB 3.0 is no support from the operating system. While this, you must install additional drivers from the vendor in order to support the USB 3.0 technology.

From exposure to the above, it can be concluded that the differences are quite striking between USB 2.0 and USB 3.0 is the level of data transfer speed, ie 400 Mbit / sec for USB 2.0 and 5 Gbit / sec for USB 3.0.
