Has been tangled into the HUB hub, because some time ago to start the Dell U2417H monitor, the monitor side comes with two USB3.0 interface, originally wanted to not need to buy HUB, but the side of the USB interface can not drag Mobile hard disk, U disk no problem! Because it is necessary to frequently use the USB interface, it is still necessary to start a HUB hub, but also with a power supply, so that you can drive more than one mobile hard disk. Looking for a long time on the Internet, but also looked at a number of brands, and finally to start with the Oerlikon this look value and appearance of metal materials, before buying some of his products, the impression is not bad. Conventions first link, the last search link â–¼ ORICO ORICO A3H4_ Taobao search Taobao search is the most intelligent commodity search engine, through the operation of big data, an accurate understanding of goods and users, to provide accurate personalized search experience. Direct links to s.taobao.com My starting price, can refer to the following â–¼ Unpacking After removing the packaging, you can see the product introduction of ORICO A3H4. The whole thing is in English. ORICO is ready to step out of Asia and go global to take the international route? â–¼ The side is also a string of English â–¼ Open the outside layer, this yellow paper box â–¼ Open to see HUB's body and adapter power â–¼ The next layer is the USB link cable â–¼ The wire is USB3.0 interface â–¼ The standard power supply specification is 12V = 2.5A â–¼ ORICO A3H4 USB3.0HUB all accessories and instructions â–¼ Appearance details ORICO A3H4 USB3.0HUB body with ORICO logo on the side â–¼ The right side of the interface are USB3.0, power supply, switch, you can also see good workmanship, the interface gap is very small â–¼ On the left are 4 fixed screws â–¼ 4 USB3.0 interface, enough for my personal use, 4 USB3.0 interface next to the LED lights, there will be a blue light after plug in the U disk â–¼ The bottom four black mats are my own DIY, it will play a non-slip effect, because Oriole this HUB is metal material, if not on a mat, on the desktop is a plan, inconvenient to insert U Disk â–¼ On-machine testing Plug in the power cord and USB cable is still relatively small and does not occupy â–¼ Press the switch button, the LED light will light up after power-on blue light, here to talk about it: every time you turn off the power and then press the power button to build the HUB will power, this design is convenient when there is inconvenience, Checked on the Internet as if his home HUB with power button is like this â–¼ After plugging in the U disk, U disk is: Flash Di CZ80 64GB and Kingston GTR G2 32GB, a speed reading speed test is also the two U disk â–¼ Plugged in after the U disk is plugged in, a blue LED lights next to the interface â–¼ First use the chipgenius software to read the HUB chip data. You can learn the information of Orcco HUB by the following picture â–¼ Then use the ATTO software to run down the speed, basic U disk running points are basically used ATTO this software to test, we can go to download backup, a very good software This is the test data of Kingston DTR G2 â–¼ The actual speed of copying large files from SSD â–¼ This is the test data of SanDisk CZ80 â–¼ The actual speed of copying large files from SSD â–¼ Link on the mobile hard disk to test the next â–¼ Actual copy file speed â–¼ I would like to think that the standard power supply specification is 12V=2.5A. It should be possible to charge the phone. However, the actual test results are not satisfactory. The following picture shows that the test data when charging my Huawei P9 is only 5V. 0.5A, this is slow, do not know how long to wait until full of electricity, rushed like a small current electronic components such as Bluetooth headset can still be â–¼ Write in the last advantage 1. The transmission rate is relatively stable, and the measured large file transmission performance is good 2 full metal body, the body itself is not small space 3.HUB has an independent power supply to ensure power consumption and stability, and the body has a switch control. Shortcomings 1. Each time you turn on the power, press the switch control to turn on the power. 2. The bottom of the fuselage is not designed with non-slip mats. If the non-slip mat on the metal surface is placed on the desktop, it is easy to slip. It is inconvenient for the user to insert and remove the U disk and data cable. ORICO A3H4 this HUB appearance is very beautiful, metal wind, the official publicity is with the MAC, the overall small and space-free, with power and four USB3.0 interface with the chassis panel of the two USB3.0 enough, the chassis Plug the U disk, HUB is still connected to the mobile hard disk, the speed of transmission with the PC USB3.0 interface speed is not much difference, ORICO A3H4 basically no loss of usb3.0 transmission performance, while access to multiple devices, do not worry The problem of data transmission speed. Well, just come here, I wish you all a happy life! ! !
