Product Features

Unique interface design and installation method:

1.90 degree interface design: The U.2 SFF - (8639) interface on the expansion line adopts a 90 degree design, which breaks the convention and allows SSDs to better adapt to different internal space layouts of the chassis when connected to the expansion line, avoiding installation inconvenience caused by space limitations and providing users with more wiring and installation possibilities in narrow or special structure chassis environments, optimizing the overall hardware layout rationality.

2.180 ° Vertical Installation Method: Supports installing SFF - (8639) SSDs vertically at a 180 ° angle in the U.2 SFF - (8639) slot. This unique installation method not only helps reduce the lateral space occupied by SSDs in the chassis, making the interior of the chassis cleaner and more orderly, but also improves the heat dissipation efficiency of SSDs to a certain extent, because vertical installation is more conducive to air circulation, takes away the heat generated by SSD operation, and ensures stable operation of SSDs.

3. Wide motherboard slot adaptability: The PCI-E 4X gold finger configured on one end has excellent compatibility and can seamlessly connect to the PCI-E4X, 8X, and 16X PCI-E slots on the computer motherboard for use. Regardless of the specifications of the PCI-E slot configuration on the user's motherboard, there is no need to worry about compatibility issues. It is easy to achieve a stable connection between the expansion cable and the motherboard, laying the foundation for subsequent high-speed data transmission and greatly expanding the product's applicability to meet the hardware matching needs of different users.

4. Excellent transmission performance guarantee: The transmission speed can reach PCle3.0 x4 full speed, up to 32G/bps, fully demonstrating its high-performance data transmission capability. Whether it is fast reading and writing of massive data, such as backup and recovery of large databases, batch processing of high-definition video materials, or dealing with professional application scenarios that require extremely high transmission speed, such as 3D modeling, deep learning training, etc., it can ensure efficient and stable data transmission, effectively reduce waiting time, and improve work efficiency.

Product Structure and Interface Introduction

U. 2 SFF - (8639) interface: Designed strictly in accordance with the U.2 SFF - (8639) standard specifications, its internal pin layout is precise and error free, and high-quality metal materials are used to create contact points with excellent conductivity and signal transmission capabilities. The 90 degree interface design ensures compliance with standard electrical connections while achieving tight integration with SSDs through clever structural design, making it convenient for users to perform plug and unplug operations in specific chassis environments. The interface shell is made of metal material and grounded to effectively block external electromagnetic interference, ensuring power supply stability and data transmission integrity.

PCI-E 4X Gold Finger: Built in accordance with the PCI-E standard, the 4X specification gold finger surface is finely gold-plated, which not only looks beautiful, but also improves conductivity and oxidation resistance, ensuring good electrical performance even after multiple insertions and uses. The length, spacing, and shape of the golden finger are precisely adapted to the PCI-E4X, 8X, and 16X slots on the computer motherboard. After insertion, it can tightly fit the pins inside the slots, achieving stable and high-speed data transmission, and building a reliable communication bridge between the expansion cable and the motherboard.

Wire section: Composed of imported wire with German patents, the core wire inside the wire is made of high-purity copper material with extremely low electrical resistivity, ensuring efficient current flow and reducing energy loss. The outer layer is wrapped with high-quality insulation material, which has good wear resistance, corrosion resistance, and high temperature resistance. It can protect the internal core wires from external environmental influences and effectively prevent signal crosstalk between different core wires. At the same time, the overall structural design of the wire is reasonable, ensuring flexibility for easy wiring while having sufficient strength, not easily broken, and extending the service life of the product.

Connector section: Made of high-quality connectors imported from Taiwan, the housing is made of high-strength engineering plastic, which has good mechanical strength and stability, and can withstand a certain degree of external impact without being easily damaged. The internal metal contact pieces undergo precision stamping and forming processes, with a smooth and flat surface, tight and stable contact with the interface. Through special elastic design, they ensure sufficient clamping force during insertion and removal without causing excessive wear to the interface, ensuring long-term reliable electrical connection.

Usage:

Install SSD to expansion cable: Align the Nvme SSD gold finger of the U.2 SFF - (8639) interface with the U.2 SFF - (8639) slot designed at a 90 degree angle on the expansion cable, and slowly insert it in a 180 degree vertical direction to ensure that the SSD gold finger is completely aligned with the pins of the slot, avoiding damage to the gold finger caused by forced insertion. During the insertion process, when you feel that the SSD is fully inserted and the slot buckle is automatically tightened, it indicates that the SSD is securely connected to the expansion cable.

Connect the PCI-E slot on the motherboard: Hold the expansion cable with the SSD installed, align the PCI-E 4X gold finger on the other end with the PCI-E4X, 8X, or 16X PCI-E slot on the computer motherboard, slowly and smoothly insert it, paying attention to the correct insertion direction. Generally, there will be corresponding markings on the slot. After insertion, ensure that the gold fingers are tightly attached to the pins inside the slot to avoid looseness and ensure the stability of subsequent data transmission.

Check the connection and startup usage: After completing the above connection steps, carefully check whether the connections between the SSD and the expansion cable, as well as between the expansion cable and the motherboard, are secure, and whether there are any loose or skewed connections. After confirming that there are no errors, turn on the computer and the system will automatically recognize the Nvme SSD with the U.2 SFF - (8639) interface. Users can partition, format, and start normal data read and write operations just like using a regular hard drive.

Daily use and monitoring: During daily use, pay attention to the working status of SSD, such as whether there is abnormal heating, significant decrease in read and write speed, etc. If any abnormalities are found, first check whether the connection between the expansion cable and the SSD or motherboard is still tight, and try unplugging the connection part again for troubleshooting. At the same time, the health and transmission performance of SSDs can also be monitored through the built-in disk management tools or related third-party software of the computer system, ensuring stable and efficient operation of the storage system.
