Product Information

USB 2.0 offers a transfer rate of 480 Mbps and USB 3.0 offers speed up to 5 Gbit/s, which is 10 times faster. Tip: If you use USB 3.0 hard drives or flash drives with your current USB 2.0 ports. They’ll work simply fine, but at USB 2.0 speeds. USB 2.0 vs 3.0 Power Management

To further complicate things, the transfer speeds themselves received names. USB 3.1 Gen 1, originally known as USB 3.0, is capable of 5 Gbps transfer speeds---that's called SuperSpeed. In terms of USB 3.0 vs 2.0 from various aspects, USB 3.0 offers superior speed and a higher efficiency power management compared to the old USB 2.0. Universal Serial Bus (USB) is an interface standard that specifies how two devices (usually a computer/phone and the other USB device) connect, communicate and exchange power. It’s a technical specification for input and output interfaces. The USB 3.0 devices contribute more power when required and conserve power when the device is connected but idle. So as for power management and power consumption, USB 3.0 is more advanced than USB 3.0. USB 2.0 vs 3.0 Compatibility USB 2.0 provides power up to 500 mA whereas USB 3.0 caters up to 900 mA, resulting in an increase in total power delivery from 2.5 W to 4.5 W (at 5 V). So as for USB 3.0 vs 2.0 charging, USB 3.0 devices can be charged faster, and USB 3.0 ports can support more power-consuming devices.Small devices can be powered directly from the USB interface, eliminating the need for additional power supply cables. These types of USB are distinguishable by their blue colored inserts and usually equipped with a 3.0 logo. MiniTool Partition Wizard Free Edition is a free partition manager& disk benchmarking tool. Its disk benchmark feature can help you measure storage performance by testing its sequential and random read/write speeds. There are two USB 3.0 speeds. The original USB 3.0 speed reaches 5.0Gbps (640MB/s), and its maximum output current is 5V/900mA. However, USB 3.0 has dual channel mode (USB 3.1 Gen1x2), which can make the speed reach 10Gbps (5Gbps per channel). The limitation is that the dual channel mode needs to use USB Type-C interface. As for Power Delivery (PD) standard, it is the successor of BC and it has almost replaced BC. The first PD version is PD 1.0 that was released in 2012. Nowadays, the PD standard has developed to PD 3.0.

DCP: Under this mode, the maximum output current is also increased to 1.5A, but you can’t use the USB port to transfer data at the same time. This mode is dedicated to charge devices. To solve this problem, Battery Charging (BC) standard comes out. The latest BC version is BC 1.2 that was released in 2010. BC 1.2 provides 3 battery charging modes:It supports plug and play. Users just need to plug a USB device into a port on a running computer, and then the USB driver will be installed and configured automatically to access the USB device. Once upon a time, USB came in two main flavors, 2.0 and 3.0. All you needed to know about them was 3.0 was faster than 2.0. You could buy a USB 2.0 flash drive and plug it into a computer that had USB 3.0 slots, and it would still work---just at the slower USB 2.0 speeds. Buying a USB 3.0 drive and plugging it into a USB 2.0 port would give you USB 2.0 speeds, too. Start a USB drive or hard drive/SSD speed test with MiniTool Partition Wizard Free Edition to get the result of USB 2.0 speed vs 3.0 now. How to choose the right USB port for different usage? Well, to find out the answer, you need to learn the major differences between USB 3.0 and USB 2.0 clearly. USB 2.0 and USB 3.0: Definition
