1. Transmission rate: U disk 3The transfer rate of 0 is much higher than that of USB flash drive 20。USB flash drive 2The theoretical transfer speed of 0 is 480Mbps, while the USB flash drive is 3The theoretical speed of 0 is up to 5Gbps. This is only the theoretical speed of the USB flash drive interface, on the whole, the USB flash drive 3The transfer rate of 0 is much higher than that of USB 20. In addition, USB flash drive 3The interface of 0 is USB 30 interface, with faster data transmission speed and higher bandwidth, can transmit data faster and improve work efficiency. And USB flash drive 2The interface of 0 is USB 20 interface, slower transmission speed.
2. Appearance design: U disk 30 is usually blue, while USB 20 is usually black. In addition, USB flash drive 3The 0 interface part is marked with "SS" style, while the USB flash drive 20 is marked with only ordinary USB universal logos. USB flash drive 3The appearance of 0 is more fashionable and more in line with the aesthetic views of modern people.
3. Socket pin: U disk 20 is designed with 4 pins, while USB flash drive 30 is designed with 9 pins. Comparatively, USB flash drive 30 is more powerful and can support more devices and application scenarios.
4. Compatibility: U disk 30 backward compatible, USB 2 supported0 devices. This means that using USB stick 30 can be compatible with more devices and application scenarios, while USB flash drive 20 can only support USB 20 devices.
5. Energy consumption: with U disk 20 compared to 30 will be more energy efficient. This means that using USB stick 30 will be more power-saving and environmentally friendly.
In short, USB flash drive 20 and 30 differs in terms of transmission rate, design, socket pins, compatibility, and energy consumption. If you need faster data transfer speed and higher bandwidth, it is recommended to choose USB flash drive 30。If you need to be compatible with more devices and support more application scenarios, we recommend that you choose USB flash drive 20。
