The USB 2.0 standard offers a theoretical maximum signaling rate of 480 megabits per second, while USB 3.0 defines a maximum rate of 5 gigabits per second. In other words, USB 3.0 is theoretically more than ten times faster than USB 2.0. ... For example, USB drives will be limited by the speed of their flash memory.

USB2 (500 Mbps), always choose USB3. If you need 2 such ports, use a hub. The maximum transfer rate of a USB2 HDD is around 30 MBps, and on USB3 still x10. 3- if you use Windows explorer this can be very, very slow, mainly if the number of files to copy is a couple of 10.000s.

Replies (2)  Most of the Hard drives are compatible with Windows 10. ... as this provides the same speed and an internal HDD. USB 3 is also preferable to USB 2, which is the slowest option, but an external HDD with USB 3 only will. still run well from a USB 2 port.

The different types of USB is simply just an improvement on technology. 3.0 is faster than 2.0 and 1.0. However, they follow the same infrastructure, so you can plug in a USB 2.0 into a 3.0 port, or vise versa, and it will function as the lower of the two.

The Thunderbolt 3 port has the same design as the USB-C port. ... It's speed allows for quicker access more data when compared to USB-C. Thunderbolt 3 works at 40Gbps while USB-C works at 10 Gbps. Thunderbolt 3 can present video content on two 4K displays or one 5k display while USB-C can present one 4K display.

The then-new USB 3.0 significantly increased the speeds of data transfer. USB 2.0 was only capable of a theoretical maximum data transfer rate of 480 megabits per second, while USB 3.0 was capable of 5 gigabits per second, or over 10 times faster. ... The data transfer speed of USB 3.1 is incredible – 10Gbps.

Check for any labels on your ports that are marked as 1.0, 1.1, 2.0, 3.0, or 3.1. The version number specifies how fast USB devices can transfer files. A USB port with just the USB symbol labeled is typically a USB 2.0 port. If the USB port has “SS” (or “SuperSpeed”) on its label, it's a USB 3.0 port.

The USB 2.0 is ideal for multimedia and storage applications due to the additional bandwidth it can provide when compared to the original USB cable. It also has a data transmission speed up to 40 times faster than USB 1.1. In practice, the actual throughput for USB 2.0 cables is typically up to 35 – 40 MB/sec.

Actually, it is not difficult to tell their physical difference. The USB 2.0 Connectors is colored white or black inside, while the USB 3.0 is colored blue inside. So if you want to find out whether the USB port on your computer or USB flash drive is 2.0 or 3.0, you can distinguish them by the USB port color inside.
