Usb 3.0 Review
Almost everyone of course get to know and use the Universal Serial Bus or USB is colloquially known as. The definition itself is a way of USB communication between equipment with a Host Controller (usually a PC).
This is often found on the USB printer, scanner, computer, mobile, mouse, digital camera, flash drive, etc. There was even once known USB, serial and parallel ports. But for now, the USB port has become standard communication ports.
USB 2.0
USB 2.0 technology introduced in around April 2000. To transfer speed (transfer rate), USB 2.0 can achieve a maximum of 480 Mbps. However, in practice, rarely get USB 2.0 speeds above 300 Mbps. In addition, the USB 2.0 requires a maximum of 500mA power supply. The pin plug in USB2.0 amounted to 4 pieces.
Type-type of the USB port
USB 3.0
Unlike USB 2.0, USB 3.0 technology was introduced since 2007. Excellence lead by USB 3.0 when compared to USB 2.0 data transfer is the speed (transfer rate) which is capable of up to 5 Gbit/s. Wow, almost 10 x folding USB 2.0 right? The other difference is the length of data cable problem. If on USB 2.0, you suggested to add cable length with a maximum of 3 M to keep data transfer speed remains accurate. In USB 3.0, cable length is no longer a factor that affects the speed of data transfer. In addition, the USB 2.0 requires maximum power supply of 900 mA.
Another advantage compared with USB 3.0 USB 2.0 is its full duplex, meaning that USB host can perform send and receive the data continuously. As for the pin plug, pin USB 3.0 has amounted to 5 pieces.
Weakness of USB 3.0
One of the flaws is no USB 3.0 support from the operating system. In the meantime, You need to install additional drivers from its vendors are in order to support the USB 3.0 technology. In addition, a new bit of hardware (hardware) which already support USB 3.0. Therefore, only a little of people who have tasted 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 rate of speed data transmission, IE 400 Mbps for USB 2.0 and 1 Gbit/s for USB 3.0.
