Nowadays USB3.1 has become the standard interface of motherboards and mobile SSDS, but many students do not know USB3.1 interface very well, nor do they know the difference between USB3.1 and 3.0, in order to let everyone distinguish USB3.1 and 3.0 better, The following source of rich lianying xiaobian to explain the difference between USB3.1 and 3.0.

The differences between USB3.1 and 3.0 interfaces are as follows:

Power: Compared with USB3.0, USB3.1 improves the power supply standard from 5V/0.9A to 20V/5A. The 100W power enables USB3.1 to greatly improve the charging speed of the device.

Transmission speed: The main upgrade to the USB port is the transmission speed, USB 3.1 already supports up to 10Gbps transmission rate, compared to USB3.0 5.0Gbps, has been doubled. Support for expansion: USB 3.1 added USB A/V video transmission.

Data encoding: Compared to USB 3.0, the new USB technology uses a more efficient data encoding system and provides more than double the effective data throughput rate. It is fully backward compatible with existing USB connectors and cables.

USB compatibility has always been good, and the USB3.1 specification inherits that. USB3.1 is easily compatible with USB3.0 and USB2.0 devices with only one adapter cable.
