ORICO (Aurico) is a brand under Shenzhen Yuanchuang Times Technology Co., Ltd. It is a world-class digital accessories brand integrating R&D, production, sales and technical services. It has now become the most influential leading brand for hard disk storage peripherals in China.
is becoming thinner and thinner as the notebook becomes, and the interfaces are getting fewer and fewer. ORICO has launched the four-port USB3.0 hub , making up for some situations where it cannot be used for multiple ports. This product model M3H4 is a pity that it cannot be used with USB3.1 with power version.
1. Unboxing

The usual simple kraft paper box, coat color sealed envelope. The back of the packaging is the product name, manufacturer contact information, product certification and QR code, etc.
pull out the outer envelope, the original color kraft paper box.
lightly open the upper cover to reveal the true face of Mount Lu. The four items in the
packaging box are packed in a matte dust-proof plastic bag.
hub USB3.0 specification, can meet the use of 4-port hubs. There are two anti-slip foot pads on the back of
.
two sides are facing each other, and there is a USB3.0 online mother socket on the left. Compare
with one yuan coin and feel the cross-sectional size.
Remove the anti-slip pad and unscrew the four screws. Two longer self-tapping screws are fixed to the internal PCB bracket, and the other two shorter ones are directly fixed to the aluminum alloy shell. After disassembling
, I suddenly found that this main control chip is different from the models that have been disassembled by electric fans! This is the low-power and high-performance USB3.0 Hub master developed by Realtek (Realtek) in 2011. The brief description of the main control chip of
is marked in the red box to support BC1.2 and Apple2.4A charging functions. Unfortunately, this is not USB3.1 version and does not come with a power connection. The computer interface cannot provide high current, so it cannot be used as a multi-port and multi-compatible charger. Unfortunately! When the computer terminal and the hub terminal (connected to mobile hard disk and USB drive) are connected to Ipad air2, the computer can provide more than 1A of current power supply.
2. Test
1. Computer system overview
. Microsoft Surface Pro4 has only one USB3.0 interface! This situation is very suitable for this product.
Microsoft Surface Pro4's system working environment is shown in the figure.
Surface Pro4 lists only one USB3.0 interface, and the red box is the identification of the ORICOUSB3.0 hub - a general SuperSpeed USB hub. Judging from the name, the data transmission rate should be good! Please read the specific performance.
The driver date automatically recognized by the computer: 2017/10/24, the program is relatively new.
Insert two USB drives and mechanical mobile hard drives for testing, and are both recognized as USB mass storage device .
2, data test
computer itself read and write speed.
on the left is the test data of the USB flash drive directly inserted into the computer, and on the right is the data measured by connecting to the ORICO USB3.0 hub. The data of the two are close, which is not bad.
on the left is the test data of the mobile hard drive directly inserted into the computer, and on the right is the data measured by connecting to the ORICO USB3.0 hub. The performance of the two is similar.
3. The actual application
is copied from the computer to the USB flash drive. Also on the left is the data inserted directly into the computer by the USB drive - the speed is about 23.5MB/sec, and on the right is the data connected to the ORICO USB3.0 hub - 23.6MB/sec, which is comparable.
Copy 2.03G movies from the computer to the mobile hard drive. On the left is the data inserted directly into the computer by the mobile hard drive - the speed is about 76.9MB/sec, and on the right is the data connected to the ORICO USB3.0 hub - 77.2MB/sec, which is basically the same.
connected to the mobile hard disk and USB drive on the ORICO USB3.0 hub transfer data to each other: the speed of transfer from the mobile hard disk to the USB drive: 67.4MB/sec.
connected to the mobile hard disk and USB drive on the ORICO USB3.0 hub transfer data to each other: the speed of transfer from USB to mobile hard disk: 76.4MB/sec.
This is the case when the same file is copied from the computer to the USB flash drive and the mobile hard drive at the same time. The total speed reaches 61.7+75.9=137.6MB/sec. There are no more devices, and the data transmission at the same time of four ports should be more ideal!
Summary
USB 3.0's theoretical speed can reach 5Gbps per second, about 625MB per second. Affected by devices, interfaces, etc., the actual transmission speed does not meet the above standards. However, through comparison, it was found that this hub has achieved the actual application speed of USB3.0. Compared with the direct connection to the computer, it has not become a system bottleneck. Although the control chip of the Orico M3H4 four-port USB3.0 hub in my hand is different from other versions, it seems that the speed can meet the current high-speed transmission needs of USB3.0 devices, which should be a powerful tool at work.
Finally, I would like to remind you if you just use it to expand the USB interface for your laptop and plug in the USB drive. This product is cost-effective and worth buying; if you use it to connect multiple mechanical mobile hard disks to copy information, it is more appropriate to choose the USB3.1 version with power supply, reducing the probability of damage to the hard disk due to insufficient power supply of the laptop.
