PCIe 4X to U.2 SFF-8639 NVMe Adapter Interface for 2.5 NVMe SSD

‌The PCIe 4X to U.2 SFF-8639 NVMe Adapter is a hardware interface that allows the connection of a 2.5" NVMe solid-state drive (SSD) to a PCIe slot on the motherboard. It facilitates the use of U.2 (SFF-8639) drives in systems that may not have native U.2 support but have available PCIe slots. This adapter is commonly used in workstations, servers, and high-performance computing systems.
