Everyone will use the USB interface. Whether it is a computer or a mobile phone, you don't really notice whether it is an interface of 2.0 or 3.0, but you can use it on the 2.0 interface when you need to transfer large files. At that time, you will certainly complain about the speed of transmission, such as snails. In fact, USB2.0's maximum transmission bandwidth is 480Mbps (ie, 60MB/s), and USB3.0's maximum transmission bandwidth is up to 5.0Gbps (625MB/s). Of course, USB 3.0 is more advanced, but sometimes (my Lenovo one) is not on the front panel or the side of the computer, but behind the computer. It is troublesome to use. Moreover, the number of interfaces is small, and it is really troublesome to use multiple devices at the same time. The emergence of orico/ORICO's M3H4-SV 4 Pro USB 3.0 hub will solve this problem.
Fresh packaging, double layer, outer white, front name and product renderings.
The back is corporate information.
Open the inner carton and you can see that the hub is wrapped in the film.
Product List: Hub, USB cable, manual, warranty card, certificate.
Look at the accessories, USB cable, a length of 1 meter, daily use is sufficient.
The plastic sheet in the middle of the USB port is blue, indicating an interface of 3.0, and the 2.0 interface is white or black.
The port's dial pad is printed with orico's logo.
Instructions, detailed usage methods and product performance introduction, but this type of product should not be used to read the manual
Front view of the M3H4-SV product, with four USB 3.0 ports in the middle, the blue plastic sheet inside the USB port indicates its 3.0 characteristics, surrounded by white plastic parts, and the port assembly is made of aluminum alloy. The logo of the product is carved in the lower right corner of the front.
The official description of the aluminum alloy shell is that after sandblasted anodizing, you can see that the matte texture is really strong and forms a strong contrast with the glossy plastic components around the USB port.
Looking at it from another perspective, the texture of the aluminum alloy shell is clearly visible, and there is a feeling of very small particles. Due to the thermal conductivity of the metal material, the cold feeling is immersed in the skin through the fingertips.
There is a small hole on the left side of the USB interface, which is the indicator light hole, which is blue when the power is on. The top matte texture aluminum alloy housing reflects the light very softly and the visual effect is very comfortable.
The matte texture of the aluminum alloy shell not only has a fine grainy feeling when touched, but in fact, it can be viewed carefully and can also detect the fine particles on the surface. The logo in the lower right corner is seamlessly printed on the aluminum alloy case, and the texture is delicate.
The M3H4-SV uses a 15-degree ergonomic bevel design. The USB hub is located on the left side. The left side is shaped like a whistle, while the female mouth is located in the center of the whistle. The same blue plastic piece is inside the port.
The other side. The circular area has a radiographic texture.
The use of a different treatment from the panel matte, so this effect is reflected under the light.
The size of the back is smaller than the main body, creating a sense of ladderiness, increasing the aesthetic effect, and having a qualified label on the back. The two large non-slip pads are very eye-catching.
Non-slip mat plastic material, good softness, rhombic texture surface treatment, there is a good non-slip effect.
With the accessory cable, the USB port is inserted and plugged smoothly with moderate tightness.
Today's computers, whether they are laptops or desktops, basically provide USB 3.0 interfaces, but the number is normally no more than two. My Lenovo all-in-one is two such ports, and its location Is behind the computer, compared to laptops, its use is very inconvenient, think about inserting equipment from behind, operating that trouble. Of course, the small number is another problem. Now that there are too many external devices, how can two of them be sufficient? ORICO M3H4-SV will be able to solve these problems perfectly. The position will be randomly placed, and the number will be changed. It.
USB3.0 is compatible with USB2.0, so in actual use, mobile hard drives, USB flash drives, mobile phones and other smart devices can be accessed.
The 15-degree bevel design is very easy to operate, and the spacing of four USB ports will not have any effect on the dialing of adjacent devices.
The USB3.0 device used is Seagate Core Wing 1T mobile hard disk, and the computer is Lenovo's all-in-one computer. It uses the CrystalDiskMark software to perform the test. The left data is the data measured after the mobile hard disk is directly connected to the USB 3.0 port on the computer. The right side is the read/write speed measured after connecting Oricore M3H4-SV. In addition to the error, it can be seen that the two values ​​are very small in value, and the read/write speeds are all about 116MB/S. It can be seen that connecting Oerlikon M3H4-SV does not reduce the read/write speed of the device, and the data measured by each port is not relevant. Using multiple devices at the same time will not reduce this speed.
USB3.0 port is also compatible with the 2.0 port, so it also uses the computer's USB2.0 port for testing, the results found that the use of Oreco M3H4-SV on the right, the read and write speed will have some decline, but want to Think of it as being designed for the 3.0 port. Using it on the 2.0 port may be equivalent to adding a device and causing a slight drop in the read/write speed. At the same time, it can also be seen that the USB 3.0 reading and writing speed is indeed much faster than the 2.0 reading and writing speed.
The appearance of the aluminum alloy is very good. The tilted panel presents a better appearance and is easy to use. With four USB 3.0 ports, you don't have to dial the ports of the computer frequently. The quantity also meets the requirements of general use, no matter if you are a desktop or Laptops can be perfectly matched. At present, the official mall sells for $99. A friend who likes to get started quickly.
