![]() USB 3.0 provides efficient power management with increased power delivery.The power management of USB 3.0 standard is much efficient compared to the 2.0 standard.Note: We can use USB 3.0 drives with a 2.0 port it will work fine but will work at the speed of 2.0 only. USB 3.0 standard devices are much suitable if there is a requirement for high-speed data transfer, but for general use, the 2.0 standard products are also good.The products of USB 2.0 standards are less expensive than the products of USB 3.0 standards. The price is also the big factor to differentiate between both the standards.Such as the USB drive's speed depends on the speed of their flash memory. However, it's the theoretical number of speed and practically it depends on specific drives.10 times) than 2.0 and can transfer the data at the maximum rate of The data transfer rate of 3.0 standard is much higher(approx. ![]() This rate is very slow for the data transfer, but it is sufficient to connect peripheral devices such as Keyboard, mouse, headset, etc. The transfer rate of USB 2.0 is a maximum of 480 Mbps(Megabytes per second).The data transmission speed of USB 3.0 is extremely faster than USB 2.0, which makes it more suitable for today's devices to enable high-speed data transfer. The data transfer speed between both standards is one of the major differences.The five extra wires in USB 3.0 allow the two- ways or full-duplex communication and also increases the bandwidth.On the other hand, the 3.0 standard contains a total of 9 wires. The USB 2.0 contains four connector wires, which support half-duplex communication. The other physical difference is the number of connection wires.The USB2.0 connectors are of white & black colored inside, whereas USB3.0 is usually of blue colored inside. In both USB 2.0 and USB 3.0, there are some physical differences, due to which anyone can easily identify both of the standards.There are five major factors by which we can differentiate the USB 2.0 and USB 3.0, which are given below: 1. Main 5 factors to differentiate the USB2.0 and USB3.0 The USB 3.0 standards can be distinguished by their blue-colored inserts and also has a 3.0 logo on them. In 3.0 standard, USB Type A, Type B, Micro-A, and Micro-B, are the supported connectors. There are various types of USB 3.0 connectors, which allow connecting two devices together. The USB 3.0 has two updated versions, which are USB 3.1 and USB 3.2. It provides much faster data transfer compared to the USB 2.0 standard. Most of the new electronic devices and computers support this USB standard to enable faster communication between the devices.ĭevices that support & use USB 3.0 can transmit the data at a maximum speed of 5Gbps. USB 3.0 is another USB standard, which was released in the year 2008. The USB 2.0 standard provides support for the USB Mini-A, USB Mini-B, and USB Mini AB connectors. The devices that use USB 2.0 can transfer the data at a maximum speed of 480Mbps, which is faster than the USB 1.1 standard and slower than the USB 3.0 standard. Almost all the devices with USB compatibilities support USB 2.0. USB 2.0 is USB standard and is also known as the high-speed USB. The first USB standard was released in the year 1996, and today there are four versions of USB specifications, which are USB 1.x, USB 2.x, USB 3.x, and USB 4. The USB connectors can also be used as the power transmitting cables such as to charge the mobile phone or tablets and these connectors are replacing the other traditional types of charger cables. #USB 2 VS USB 3 POWER REQUIREMENTS SERIAL#USB or Universal Serial Bus is a connecting interface standard that enables the computer or other electronic devices to connect and communicate with other peripheral devices such as Keyboard, MIC, Mouse, flash drive, etc. Before starting, let's understand what USB and its specifications are. In this topic, we will see the differences between USB 2.0 and 3.0 and what are new advanced features are there in 3.0, which are not in 2.0. Nowadays, most computers and other electronic devices are using USB 3.0 instead of 2.0 due to various advanced features of USB 3.0. ![]() USB 2.0 and 3.0 are the two specifications of USB ( Universal Serial Bus) that are used for connecting peripheral devices to the computers. ![]() Next → ← prev USB 2.0 vs 3.0 | Difference between USB 2.0 and USB 3.0 ![]()
