With the growth of computing power and speed of SSDs (solid-state storage device, the SSD) increasingly have the ability to traditional hard disk drives (hard disk drives, HDDs) to compete in the market.

Including connectors, including technological advances have eased the SSD early in the many disadvantages of cost and storage capacity, as more and more design engineers in order to obtain better performance in favor of the SSD connector technology must keep pace . The connector is the bridge between the circuit and allows current to flow seamlessly through the circuit, thus completing the intended function. The connector design requires a high level of conceptualization and design strategies, in order to meet the mechanical and electrical performance requirements of the SSD and data communications industry. Connection's innovation and sound engineering principles not only to promote a higher level of intelligence of the design, but also help to ensure that the design by the SSD interconnect scheme has the best performance, ensure the safety and long-term reliability of electronic circuits. Mini SAS 1.8-inch hard drive appeared to bring the development of the small size of interconnect products, small connector with sufficient performance headroom to meet future critical enterprise-class storage connectivity requirements.

 The micro SAS connector is the industry's smallest, for 1.8-inch drives, the next generation of high-speed serial I / O solutions, data rates of up to 6Gbps. The increased density and performance, dual stack and dual stack at right angles to a micro SATA / SAS connectors have been used in the 1.8-inch drives, to increase density and provide adequate electrical performance. SATA / SAS connectors to increase the many special features to improve performance, including the sharing of the ground, staggered terminal design, as well as terminal bending design to improve performance. The benefits of the dual-stack stacking connection of two 1.8-inch drives, thereby increasing the density of drive, and dual-stack Molex connector electrical performance compared to standard designs are much higher. It adds a postmark terminal as specified differential line between shared ground in order to reduce the coupling between them. This shared ground pins up and down two sets of socket used to connect as shown below, is essential for achieving high-speed electrical performance, as a large ground plane, can shield the coupling between two high-speed differential pair . Repeat the iterative design (iteration,) to minimize permanent deformation, which helps to optimize the design of dual-stack connector terminal. High-quality interconnect design and engineering to ensure that the electronic equipment and device manufacturers to maximize performance, reliability and safety of their products, to expand sales, increase customer satisfaction.
