How much do you know about hubs? Teach you how to choose USB HUB!


Post time: Oct-22-2021

The USB hub, which we often call USB HUB, can extend the USB interface of the computer to multiple USB interfaces, so as to solve the problem that the USB interface of the user’s computer is not enough and is convenient for plugging and unplugging the interface.

How to measure a good HUB standard? The word “good” has multiple meanings, and only a good USB HUB is a good USB HUB that requires a comprehensive evaluation of quality, ease of use, and brand.

Based on the experience of buying hubs from our friends, today we will talk about the basic qualities of a qualified USB HUB, which features are needed?

1. Number of interfaces

At present, the 4-port USB HUB is widely used, and there are 7 ports, and there are more than a dozen HUBs. Of course, such HUBs are mainly used for work scenarios that require comparison, verification, and batch processing. It is worth mentioning that the multi-interface USB HUB generally has a power supply, which has obvious advantages in power and can drive more devices with high power supply requirements.

2. External power supply

First of all, we must understand this attempt. A USB interface can provide 500mA of current. A HUB without an external power supply can only distribute the limited 500mA current and distribute it to each expansion interface. The external power supply HUB does not have this limitation, and can provide sufficient power for each interface according to the active condition, which is very helpful for devices such as USB mobile hard disks with high power supply requirements.

It is necessary to know that insufficient power supply will cause the device to be unable to read the data, and the serious point will lead to data recording errors, hard disk damage, scrapping and other conditions.

3. Transmission speed

The problem of hub transmission speed is not absolute. In addition to theoretical value, cable length, power supply, and compatibility between USBs, it will also affect transmission signal problems. The theoretical maximum transmission speed of USB2.0 is 480Mbps, while the theoretical speed of USB3.0 can reach 5Gbps. Popularly speaking, USB3.0 is nearly ten times faster than USB2.0 charging/transmission speed.

But if you are using a 2.0 USB flash drive, you can only reach the 2.0 transmission speed if you connect to the USB3.0 interface. The version of the USB flash drive has been limited.

4. reasonable interface layout

An excellent USB HUB is very user-friendly in design, taking into account all aspects of the user. For example, the location of the expansion interface provided by the USB HUB is very important. Once a USB port with a bad location is inserted into the device, it may block other USB devices and cause a waste of the interface. (Think of those anti-human socket designs)

Generally, the USB HUB interface of the star-shaped open design is in a very good position, and there will be no conflicts. The superior brand has taken this into consideration, so this concept is incorporated in the development and design. Some of the superior ones have launched in the market. This is not the case with products.

5. reasonable lighting tips

In order to identify the working conditions of each device on the USB HUB, many USB HUBs provide LED lights to display the working status. Generally speaking, the steady light means that the USB device is being connected stably, and the light flashing indicates that the USB device is transmitting data.

This prompt effect is very practical. It is worth noting that some USB HUB’s lighting effects are too obvious and easily cause light pollution, so reasonable lighting prompts are the key, and the lighting should be soft and not dazzling.
