1. This M.2 to U.2 adapter card converts the M.2 interface on the motherboard into a standard U.2 (SFF-8639) interface and supplies power through the 15-pin SATA power connector, ensuring fast and stable data transmission. Drive-free, plug and play. 2. U.2 SFF-8639 interface: provides one U.2 (SFF-8639) interface, allowing connection to high-performance 2.5-inch NVMe U.2 (SFF-8639) SSDs and other devices with a U.2 (SFF-8639) interface. Theoretical bandwidth reaches up to 32Gbps. No external U.2 data cable required. 3. M.2 (M-key) interface: features an M.2 (PCIe Gen x4) channel interface with a theoretical bandwidth of up to 32Gbps. Simply insert the adapter card into the motherboard's M.2 (M-key) slot and connect to an NVMe U.2 (SFF-8639) SSD for high-performance data transfer. 4. Saves motherboard space: enables larger storage capacity and allows the NVMe U.2 SSD to be installed in various locations within the chassis. Note: M.2 PCIe SSD and M.2 SATA SSD use the same connector type; this adapter is compatible only with M.2 connectors designed for M.2 PCIe SSDs. 5. System requirements: compatible with Windows and UEFI 2.3.1 or higher.
