The MCIO 74 P to 2 X SFF-8639 U.2 Cable - 50CM is a cable designed to connect devices that use the U.2 interface to a motherboard or host controller. The cable has a length of 50 centimeters, making it suitable for connecting devices within a reasonable distance. The cable features a MCIO 74 P connector on one end and two SFF-8639 U.2 connectors on the other end. The MCIO 74 P connector is typically used to connect to the motherboard or host controller, while the SFF-8639 U.2 connectors are used to connect to U.2 compatible devices such as solid-state drives (SSDs). The MCIO 74 P connector is a multi-lane connector that allows for high-speed data transfer between the motherboard or host controller and the connected devices. It provides a reliable and secure connection, ensuring efficient communication between the devices. The SFF-8639 U.2 connectors are commonly used in enterprise-grade storage systems and high-performance computing environments. They support the U.2 interface, which is a small form factor connector designed specifically for high-speed data transfer in storage devices. U.2 connectors provide fast data rates, low latency, and high reliability. The 50-centimeter length of the cable allows for flexibility in positioning the connected devices within a system. It provides sufficient reach to connect U.2 devices placed reasonably close to the motherboard or host controller. Micro SATA Cables Part#MCIO-2048-2XU2
