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 In general, the speed of USB 2.0 drive is not more than 60 MB/s and the speed of USB 3.0 is not more than 500 MB/s. The accurate time it takes to transfer a file size of 1GB on a USB 2.0 and a USB 3.0 drive should fluctuate depending on the actual drive speed and computer condition.

Tip: To perform 4KiB read/write test (the speed at reading/writing small files of 4 KB in size), you can choose two 4KB in the Transfer Size interval. Note: USB 1.0 is now renamed USB 2.0 LowSpeed, and USB 1.1 is renamed USB 2.0 FullSpeed. Therefore, their speeds are also USB 2 speeds. USB 2.0That passion continues today. Josh has outfitted his house with a wide variety of smart gadgets, ran Ethernet cables everywhere, assembled Plex servers, and even built a smart mirror with just a frame, some electronics, a Raspberry Pi, and open-source code.

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. However, nowadays, these interfaces have been substituted by USB interface. Currently, the USB interface is widely used in information, communication, and photography products like PCs, mobile devices digital TV (set-top boxes), game consoles, etc. Step 4. When Disk Benchmark finishes, it will present you the transfer speed test result with a complete graphical result, as you can see from the following screenshot. In general, when you transfer files between two USB peripheral devices like mobile phones, players, etc., you can’t bypass PCs. This is very inconvenient. Fortunately, USB OTG can turn USB peripherals into USB hosts so that two USB peripheral devices can communicate with each other without PCs. Small devices can be powered directly from the USB interface, eliminating the need for additional power supply cables.The USB 3.0, also named USB 3.1 Gen1/USB 3.2 Gen1, was released in 2008. It adopted a design of 9 pins—among them, the first row of 4 pins is the same as USB 2.0, and the second row of 5 pins is specially prepared for USB 3.0. Therefore, you can distinguish between USB 2.0 and USB 3.0 through the pins (USB 2.0 only has 4 pins). The USB Implementors Forums (USB-IF) maintains USB specifications and compliance, and it's behind the naming schemes found on USB cables and devices. When it introduced USB 3.1, rather than keep things simple and let that name differentiate from USB 3.0, it called the new standard "USB 3.1 Gen 2." USB 3.0 was retroactively renamed "USB 3.1 Gen 1."

After seeing the above USB 3.0 vs 2.0, do you know their main differences? If you do, you should know how to make a choice between the two now. if you want to test the transfer speed of your USB 3.0 devices, you may use MiniTool Partition Wizard Free Edition to perform disk benchmarking. 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. 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. USB 2.0 has a total of 4 connector wires, supporting half-duplex communication. As for USB 3.0, it has a total of 9 connector wires. With these five additional wires, it increases the bandwidth of USB 3.0 by permitting two-way communications simultaneously. USB 2.0 vs 3.0 Speed USB 3.0 speeds not only make the data transmission more time-saving, but also enough for the desktop operating system to be installed and run smoothly on the USB flash drive and portable hard drive.Before USB came out, connecting different devices to computers required different types of interfaces. For example: In the USB 2.0 era, the USB interface can provide 5V@500mA=2.5W of power. However, due to the rapid development of portable peripherals, especially smart phones, the demand for using the USB interface to charge the batteries of portable devices has increased. USB 3.0 was released in November 2008, which is the third major version of the Universal Serial Bus standard for interfacing computers and electronic devices. USB 3.0 has gradually become the new standard for USB devices by providing a lot of improvements over USB 2.0. 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. Apart from data transmission, USB interface has other useful functionalities such as battery charge, video and audio data transmission, etc. In the following content, I will introduce them to you.
