The technical standard USB3.0 was launched at the end of 2008, but it has not been popular for a long time. After all, it will take some time for a technology to develop from the standard to the real promotion. The old desktop computer in my home only provides a USB2.0 interface. The computer I use in the company also gradually has a USB3.0 interface in 2014. USB3.1 was born at the end of 2013, but actually we are still unfamiliar with this standard. We do not know much about USB3.1 technology at present, whether on storage devices or various interfaces.

USB 3.1 is the latest USB specification, which was initiated by Intel and other companies. The data transmission speed can be increased to 10Gbps. Compared with USB 3.0 technology, the new USB technology uses a more efficient data encoding system and provides more than twice the effective data throughput. It is fully downward compatible with existing USB connectors and cables. USB3.1 is compatible with the existing USB 3.0 software stack and device protocol, 5Gbps hubs and devices, and USB 2.0 products. (Note: this paragraph is quoted from the network)

The thing that bothers me all the time is that my computer doesn't even have a high-speed USB 3.0 interface. I temporarily feel it is not appropriate to replace the USB 3.0 motherboard. Fortunately, I got a product from ORICO, which helped me a lot. The old computer in my home also has a new look. It has passed USB 3.0 and directly upgraded to USB 3.1.

The package of this ORICO PA31-2P USB3.1 expansion card is different from the environment-friendly kraft paper package that ORCIO has always used. The overall package of the expansion card uses black color. Compared with the packaging of other ORICO products, this outer package is more exquisite. The front of the expansion card package is the product's LOGO and speed. The side also provides some basic information of the product. The pattern printed on the back of the product shows that the product is applicable only to desktop computers.

For board cards and PCB products, anti-static requirements are very high, so the expansion card uses anti-static packaging, the product packaging uses anti-static bags, and the anti-static seal uses yellow anti-static labels.

The expansion card provides a board, two screws for fixing, a drive disc of the product, a simple instruction manual and a certificate of conformity.

The overall design of the expansion card is a black PCB. The expansion card uses black oil solder mask. The product model is printed on the PCB of the product. The interface of the expansion card uses the PCI Express interface, which can be conveniently used on the PCI Express X4, X8, or X16 expansion slots. It can support all the main boards on the basic market. The most commonly used SATA power supply port is used for power supply of the expansion card, and the capacitance of the expansion card is designed with solid state capacitance, which helps the stable operation of the expansion card. The main control chip adopts ASMedia's USB3.1 main control chip, which helps with high-speed transmission.

The expansion card provides two USB3.1 interfaces, which can basically meet the needs of users using USB3.1 storage devices. The expansion card adopts a standard design, so it can be used normally for any standard chassis.

The back design of the expansion card is very clean. It can be seen from the PCB design that ORICO's PCB design and wiring are reasonable, and the black gold plating process is used for production, which provides a guarantee for stable operation.

My computer has two PCI Express slots, but I can't use PCI Express X1 for the time being, so I can only use the slot often used by the graphics card.

The power supply of the expansion card uses the power supply port used by sata. It is very easy to find the corresponding power supply port in the computer.

The expansion card of the computer is a standard interface, and ORICO expansion card provides two USB3.1 interfaces.

The driver of the Asmedia USB must be installed on the expansion card, which can be downloaded from the Internet. If the host has an optical drive, you can also install the driver directly using the CD that comes with the expansion card. After installation, you can see the device in the Device Manager.

The above three pictures show the USB 3.1 transmission speed of the expansion card, the USB 3.0 transmission speed of the computer and the USB 2.0 speed of the computer. By copying the win7 image file, that is, the copy of a large file, we can see that under USB3.1, the copy speed is very fine and very fast, and the copy speed of the same file using USB3.1 is basically more than twice that of USB3.0. The speed of USB2.0 is indeed slightly slow.

Summary

Through the author's practical experience, the ORICO PA31-2P USB3.1 expansion card can easily make the old motherboard shine through the PCI Express slot, and old computers can also enjoy the speed of USB3.1. ORICO PA31-2P USB3.1 expansion card adopts all solid state capacitor design with excellent materials. The PCB design adopts black gold plating process with first-class workmanship, which provides guarantee for stable and reliable operation of user expansion USB3.1.
