what is USB 3.0 HUB?

USB 3.0 hub

The USB 3.0 standard presented in 2008 promised a drastically increased data throughput rate compared to the technological predecessor USB 2.0. Due to the fact that USB 3.0 is compatible with previous technologies, older devices are still able to be used with a new USB 3.0 hub.

Why should a USB 3.0 hub be used?

There are many reasons why you should use a USB 3.0 hub. One of those reasons is that you have to think about the future of technology. Sooner or later, end devices that only support the USB 2.0 standard will disappear from the market. This is all the more important when you consider that an innovation has already been developed, which is called  USB 3.1  ( SuperSpeed ​​+ ). USB 2.0 is therefore declining and can be ignored, since a USB 3.0 hub can also handle end devices with 2.0 technology anyway. If new end devices with a USB connection are purchased, they are usually already supplied with USB 3.0.

If you buy a USB 2.0 hub and have end devices that support USB 3.0, you can use them, but then you have to do without the enormous speed advantage of USB 3.0. That makes no sense technically or economically. If a hub is to be integrated into the existing infrastructure, the choice of a USB 3.0 hub is highly recommended.

How fast is the data transfer via a USB 3.0 hub?

The transfer rate of a USB 3.0 hub depends on several factors. In order to achieve the maximum possible speed for data transfers, it is imperative that all components and devices involved support the USB 3.0 standard. For example, in order to drive an external hard drive to achieve maximum performance during write and read access, the USB port on the mainboard, the USB hub and the external hard drive must be explicitly designed for USB 3.0. This can be seen from the blue elements inside the plug and USB slots.

What happens if I connect a USB 2.0 device to a USB 3.0 hub?

In principle, nothing can happen that would damage the USB 3.0 hub, the end device or the mainboard. However, you have to live with a significant drop in speed if one of the elements mentioned does not support USB 3.0.

Is there a USB 3.0 hub that offers a special range of functions?

There is actually such a USB 3.0 hub. Different versions are available. Some support WLAN, others have a  card reader  integrated and thus not only function as a central element for the connection between USB devices, but also as a control center for reading SD cards.
