For notebook users, what is the most lacking? All types of interfaces. As an electronic design engineer, the most annoying thing for my staff to use the notebook to debug the system on site every time is that the notebook interface is too tight. In order to pursue thinness, the current notebook will simplify the interface as much as possible, not to mention the COM interface that I often use, even the USB interface is too few. The Bluetooth mouse and keyboard occupy some interfaces. The author's RS232 to RS485 to CAN interface also needs to occupy the USB interface. At this time, the USB interface is obviously not enough. A product with high appearance, convenient expansion of USB port and auxiliary heat dissipation is one of the product types that the author has been looking forward to.

The packaging of M4U3 4-port USB3.0 multi-function expansion hub adopts a long strip design, and the front is the product style.

The back is a simple manufacturer information.

In addition to the hub itself, two sets of rubber pads are also provided as supports. Due to the separate design, an additional USB 3.0 data line is also provided.

The user manual of the product is very simple. You can basically master the key points of use after a quick glance.

In terms of data line, the product provides a public to public USB3.0 data line with a standard blue design, which is the standard interface style of USB3.0.

The hub adopts silver ABS plastic design and provides two sets of rubber pads, gray and blue, which can be selected according to your preference.

The two ends of the hub are designed in a similar wire drawing way, which makes it look better in the light environment.

The back of the product is designed with USB input and output interfaces. There is no redundant design except USB interface. From the appearance, the hub still has enough space to design other interfaces. It would be even better if it could provide the serial port that the author often uses.

In terms of interface design, there are five USB 3.0 interfaces in total, of which the first USB interface on the left is the design of the input port, and the four USB 3.0 output ports on the right are the design of the input port. The input port is marked with a simple "USB IN" to distinguish other types of USB interfaces.

The USB interface of the product is designed in the groove on the back, and the two sides of the groove adopt the design method of bevel, so there will be no abrupt or scratch phenomenon.

The rubber pad is mainly used to fix the hub. M4U3 provides two sets of rubber pads with different colors for users to choose.

The rubber pad can be used according to the needs. Of course, in order to be more reliable, the four can be used together without any problem.

However, due to the design of the groove, if you want to use two sets of rubber pads, you can only use them at the edge, because the groove opening of this product is large.

Because of the USB3.0 interface, The USB interface spacing is also designed reasonably. The USB flash disk of the author belongs to the ordinary USB flash disk type with large volume. After insertion, there is still no problem in using data cables on both sides. The spacing design is reasonable. Of course, because there is enough space on the back side, if the spacing is larger, it may be more efficient, but the lack of aesthetic estimation is inevitable.

Another important function of the M4U3 expansion hub is to serve as a support for notebook tablets. When used as a laptop bracket, the design of rubber pads on both sides makes it very stable. In addition, because the adapter of the notebook is padded high, there is more air flow space at the bottom of the notebook, and the heat dissipation effect is better.

In terms of speed, under the Win7 system, the author used two professional test software, ATTO Disk Benchmark and HD Tune, to experience the speed. In terms of hard disk, the 1T mobile hard disk introduced in the author's previous experience articles was still used. The ATTO test speed was more than 100M, and the speed was consistent with the USB 3.0 interface provided by the notebook or desktop computer. The HD Tune speed measurement results are also similar to the previous experience results.

Summary

ORICO M4U3 4-port USB3.0 multi-function expansion hub bracket can rapidly expand four USB3.0 interfaces. It adopts a long strip design, which is convenient for users to store and carry. It provides two sets of rubber anti-skid pads, which can be used as a laptop bracket. The product appearance adopts a unique surface oil injection treatment, making the hub more beautiful and more textured.
