The part "MCIO x8 74 Pin (NVMe) to 2x SFF-8643 NVMe 50 CM" is a specialized cable designed for connecting NVMe (Non-Volatile Memory Express) storage devices to a server or storage controller. It facilitates the high-speed transfer of data between NVMe drives and the controller, enabling efficient and low-latency data access in data-intensive applications. Here's a technical description of the cable: Connector Types: MCIO x8 74 Pin (NVMe) Connector: This connector is designed to plug into the NVMe-capable storage controller or server. It utilizes a x8 electrical interface, indicating it supports 8 lanes of data transmission, which allows for higher data transfer rates compared to lower lane counts. 2x SFF-8643 NVMe Connectors: These connectors are designed to plug into NVMe storage devices, such as NVMe SSDs (Solid State Drives). Data Transfer Speed: The cable is capable of supporting the high data transfer speeds associated with NVMe technology. NVMe devices can take full advantage of the PCIe (Peripheral Component Interconnect Express) interface, allowing for significantly faster data rates compared to traditional SATA interfaces. The actual data transfer speed will also depend on the specific NVMe drives and controller being used. Cable Construction: The cable is constructed with high-quality materials, including individually shielded wire pairs and overall shielding to minimize electromagnetic interference and ensure signal integrity. This construction is crucial for maintaining data reliability and reducing data transmission errors in high-speed data environments. Compatibility: The cable is designed to be compatible with NVMe storage devices equipped with SFF-8643 connectors and NVMe-capable controllers featuring the MCIO x8 74 Pin (NVMe) interface. It is essential to verify the compatibility of the cable with the specific NVMe devices and controller to ensure proper functionality. Micro SATA Cables Part# MCIO-2065-50
