1) This adapter card converts a motherboard or laptop's NGFF NVME M-Key PCI-E interface into two M. 2 NGFF Key-M NVME interfaces, compatible with NAS industrial control motherboards.
2) Note: Only applicable to M-Key NVME PCI-E interfaces, not B-Key SATA single interfaces. Supports one 2230mm and one 2280mm M-interface SSD. No external power supply required. Compact size and stable performance. 3) Both SSDs can work simultaneously; both SSDs operate in PCIe x1 Gen2 mode. 4) Built-in ASM1182e chipset, PCI Express packet switch, providing one PCIe x1 Gen2 upstream port and two PCIe x1 Gen2 downstream ports, enabling users to expand the PCIe ports of motherboards or embedded systems, compliant with PCIe Base SPEC 2.0 standard. 5) This adapter card only changes the interface of the NVME M-Key PCI-E module and does not change the module's performance.
