Technical Specifications

USB 3.2 Gen 2x2 is a standard released by the USB Implementers Forum (USB-IF) aimed at further improving data transfer speed and efficiency. Its most prominent feature is supporting a transmission rate of up to 20Gbps, thanks to its dual channel transmission mode. At the same time, the standard also maintains the same energy supply capacity as USB 3.1 Gen 2 (now known as USB 3.2 Gen 2x1), supporting up to 100 watts of power transmission, providing convenience for device charging and data transmission.

Performance Characteristics

1. High speed data transmission

• Speed improvement: The transmission speed of USB 3.2 Gen 2x2 reaches 20Gbps, which is four times that of USB 3.2 Gen 1x1 (5Gbps) and twice that of USB 3.2 Gen 2x1 (10Gbps).

• Efficiency enhancement: This improvement is particularly important for applications such as large file transfer, video editing, and high-definition content playback, significantly reducing transmission waiting time.

2. Enhanced power supply

• Power supply: Supports up to 100 watts of power transmission, can quickly charge connected devices, especially suitable for devices that require high power supply, such as laptops.


Wide compatibility: The USB 3.2 Gen 2x2 maintains backward compatibility with earlier USB versions, meaning users can seamlessly connect old devices without worrying about compatibility issues.

Hardware requirements: In order to fully utilize the performance of USB 3.2 Gen 2x2, users need to ensure that the devices (such as motherboards, external hard drives, etc.) and cables they use support this standard.

Practical Application

In practical applications, the high-speed transmission capability of USB 3.2 Gen 2x2 is particularly suitable for scenarios with extremely high speed requirements:

• Big data processing: For application scenarios that require the transfer of large amounts of data, such as data centers, large servers, etc., USB 3.2 Gen 2x2 can significantly improve data processing efficiency.

• Professional video editing: Video editing requires frequent transfer of high-definition video files, and USB 3.2 Gen 2x2 can significantly reduce file transfer time and improve work efficiency.

• High speed backup solution: For users who need to quickly backup and recover large amounts of data, USB 3.2 Gen 2x2 provides an efficient solution.

Why choose USB 3.2 Gen 2x2

The main reason for choosing USB 3.2 Gen 2x2 is its high-speed data transfer capability and powerful compatibility. For users and businesses who need to handle large amounts of data or pursue efficient workflows, USB 3.2 Gen 2x2 provides an unparalleled solution. It not only significantly improves data processing and transmission efficiency, but also ensures compatibility with various devices, thereby ensuring the long-term value of investment. In addition, as more and more device manufacturers adopt this standard, the accessories and device ecosystem of USB 3.2 Gen 2x2 will continue to expand, further enhancing its application range and practicality in the market.
