  What is a splitter used for?
  A USB splitter, also called a USB hub, is a very common peripheral device because it expands a limited USB interface from one USB interface to multiple USB interfaces.
  The multiple USB ports provided by the USB splitter can all be used at the same time. However, due to the limited power supply of the upper USB port, it may not be able to meet the needs of multiple devices that require a larger power supply. At this time, an active USB splitter can be used. The adapter can be used normally through external power supply.

  The difference between usb hub 2.0 and 3.0
  1. The difference between usb hub 2.0 and 3.0
  1. Slave transmission rate
  The theoretical data transmission rate of USB2.0 is 480M per second, while the theoretical speed of USB3.0 is as high as 5G per second, the transmission speed of USB3.0 is more than 10 times that of USB2.0. Of course, this is only the theoretical speed of the USB interface. Overall, the transmission rate of USB3.0 is much higher than USB2.0.
  2. Interface appearance
  USB3.0 is usually blue, USB2.0 is usually black. Generally speaking, every computer will have both USB2.0 and USB3.0.
  3. Socket pins
  Judging from the pins of the USB socket, USB2.0 adopts a 4-pin design, while USB3.0 adopts a 9-pin design. In comparison, USB3.0 is more powerful.
  4. USB male port
  Judging from the appearance of the USB male port, the USB3.0 interface part is marked with the "SS" style, while the USB2.0 is only marked with the ordinary USB universal logo.

  2. Which USB hub 2.0 or 3.0 is better?
  1. Service life
  The excessive speed is based on new technology, high voltage and high current, and high heat generation will naturally occur. We all know that electronic products work at high temperature will inevitably affect the lifespan, and for U disk, high heat will also cause deformation of the board, resulting in chip soldering, resulting in poor contact or even falling off of the U disk. Therefore, USB3.0 has a higher damage rate.
  2. Price and technology
  Because U2 is a mature technology, its compatibility is much higher than that of U3. USB2.0 is generally sufficient for daily use. Before u3 or even u3.1 technology matures, there is no need for everyone to upgrade them all. Not to mention spending more money, the life of the things they buy will be short.
