To distinguish the USB from the outside the port of the USB 2.0 is given the standard black color while USB 3.0 is given the blue color.USB 2.0 is lesser in price than USB 3.0.USB 2.0 is half-duplex, having only one-way communication while USB 3.0 is full-duplex.USB 2.0 is in use since its launch year, 2000 while USB 3.0 was launched in 2010.USB 2.0 is the preceded version of USB 3.0.On the other hand, because of its speed, the USB 3.0 is called super-speed USB. USB 2.0 has slower data transfer rate than USB 3.0, it is up to 10 times slower.Main Differences Between USB 2.0 And USB 3.0 USB 3.0, two more versions of this 3rd generation have been launched: USB 3.1 and USB 3.2. Though it is costly than that it’s older versions. USB 3.0 is used mostly these days because of the improved features. The USB port of the USB 3.0 is given a blue color to distinguish it from the other versions. And its cable length is up to three meters. One data path is to receive the data and the other path is to transmit the data. It is a full-duplex system and uses two unidirectional data paths. Within an endpoint, a large number of logical streams are allowed through this feature.Īlso, the bandwidth of the USB 3.0 is increased. Also, a new feature is added which is called Stream protocol. The speed of the USB 3.0 is 10 times faster than that of USB 2.0. And the power it delivers is of the amount 900 mA. The data transfer rate of this version is 5 Gigabits per second. The manufactures distinguish between the USB 2.0 and USB 3.0 by giving the USB 3.0 the initial SS, which stands for SuperSpeed. Because of its high-speed rate, it is also called super-speed USB. USB 3.0 is a much-improved version and is the 3rd version in the USB versions. Since this is an older version and there are many new versions with better features it is not used much these days. And the standard black color is used for its port to distinguish it from other versions. It is a feature that allows two USB devices to communicate with one another, and they do not require a separate USB host. And the amount of power it delivers is about 500 mA.Īlso, USB 2.0 has 4 connector wires and supports half-duplex communication. This is the maximum data transfer rate through 280 Mbps is the practical data transfer rate. The data transmission rate of this version is 480 Megabits per second (Mbps). The Speed is more of this version than that of USB 1.0. This version was better than its previous version. Hi-speed USB or High Bandwidth is also the name used for the USB 2.0. The USB 2.0 in use since April 2000, when it was launched. USB 2.0 is the second version of the USB, which is a device that establishes connection and communication between computers. Color Significance The USB 2.0 comes with the port of black color. Power It delivers a 500 mA amount of power. The maximum speed is 5 Gigabits per second. Comparison Table Between USB 2.0 And USB 3.0 Parameters of Comparison USB 2.0 USB 3.0 Launched In? It was launched in the year 2000. And it can both transmit and receive the data. Its data transfer rate is up to 5 Gigabits per second. Its speed is ten times faster than its old version with many improvements and therefore it is known as Superspeed USB. And have an On-The-Go supplement feature. Though later USB 3.0 was launched with much better features. It was a better version of USB 1.0 with better speed and features.
