Compatibility Notes  

This cable is designed for connecting U.2 SFF-8639 NVMe SSDs to PCIe 4.0 x1 host interfaces. The U.2 SFF-8639 connector is a universal interface that supports NVMe PCIe drives and is also compatible with SATA, SAS, and other protocols through the same physical interface. Ensure the host system’s PCIe slot supports PCIe 4.0 or earlier versions (3.0/2.0) for backward compatibility. The cable provides integrated power delivery, eliminating the need for separate power connectors for the SSD. Note that PCIe 4.0 x1 bandwidth may limit the maximum performance of high-speed U.2 NVMe SSDs (e.g., PCIe 4.0 x1 theoretical bandwidth is ~2 GB/s, while a PCIe 4.0 x4 SSD can reach ~8 GB/s). Verify SSD power requirements, as some U.2 SSDs may require additional power beyond what the PCIe slot provides. This cable is not suitable for SAS or SATA drives that rely solely on SATA/SAS protocols without PCIe NVMe support.  

Note: All specifications adhere to PCI-SIG PCIe 4.0 standards and SFF-8639 specifications, ensuring interoperability with U.2 NVMe SSDs and PCIe-based systems.
