2-in-1 M.2 SSD Adapter: It allows you to install one M.2 NVMe SSD and one M.2 SATA SSD on your computer. The M.2 NVMe SSD is installed in the lower slot (M Key), while the M.2 SATA SSD is installed in the upper slot (B Key).
The NVMe SSD signals go directly to the PCIe X4 interface, while the SATA SSD signals go to the SATA III interface, which needs to be connected to the motherboard's SATA interface via a SATA cable (included). These are two completely independent data channels.
