USB cables are not one-size-fits-all. You may have seen them identified by both numbers and letters. The number system is what we’re discussing here, with USB 2.0 cables and USB 3.0 being the most common.

While USB 2.0 cables are more widespread in their adoption and less expensive, USB 3.0 is the current gold standard. USB 3.0 cables offer enhanced performance, incredible speed, and efficient power management.

Getting To Know USB 2.0 And 3.0 Cables

Also called High-Speed USB, USB 2.0 cables were released in the year 2000. To this day, USB 2.0 cables remain in use for most devices and are likely the type you use every day. The transfer speed for the USB 2.0 is 480 megabits per second which is relatively fast but not as advanced as the superior 3.0 standard.

USB 3.0 cables were first released in November 2008. Even since, due to the number of improvements, USB 3.0 has become the new standard for USB-connected devices. The data transfer speed of a high-quality USB 3.0 cable is ten times faster than the USB 2.0, around 5 Gbit/s.

Differences Between USB 2.0 And 3.0 Cables

Typically, on appearances, a USB 3.0 cable will have blue coloured inserts and a logo. Comparatively, a USB 2.0 cable will have white or black inserts. Also, a USB 2.0 cable will only have four connector wires while a 3.0 will have nine. The extra wires in a USB 3.0 are used to increase bandwidth and allows for two-way communication to occur simultaneously.

The speed of USB 2.0 is sufficient to connect keyboards, mice, or headphones, however, a USB 3.0 cable will work much faster.

Prices are much cheaper for a USB 2.0 cable than USB 3.0. For general use, such as transferring small documents, a USB 2.0 is sufficient. However, if using the drive frequently or moving large documents, a USB 3.0 is recommended.

Charge time also varies between the USB 2.0 and 3.0. A USB 3.0 is more power-efficient and provides higher power delivery. USB 3.0 devices charge faster and 3.0 ports support power-consuming devices. USB 3.0 devices recognize when power is needed, and conserve power when the device is idle.

Which USB Cable Is Best?

One good thing about USB 3.0 Type-C cables is that they are backwards compatible. This means if an earlier version is connected to it, the drive will still work as normal. Depending upon one’s needs, USB 2.0 or 3.0 are both excellent choices.

While the USB 3.0 is seen as the superior choice, it is not always necessary for everyday tasks, however, you will get faster sync and charge on this advanced standard.
