GLOTRENDS PA12 M.2 PCIe Conversion Adapter: Supports one M.2 NVMe SSD and one M.2 SATA SSD.

[2 in 1 M.2 SSD Adapter]: This allows you to install one M.2 NVMe SSD and one M.2 SATA SSD in your computer. The M.2 NVMe SSD is installed in the lower slot (M key), and the M.2 SATA SSD is installed in the upper slot (B key). The NVMe SSD signal is sent directly to the PCIe X4 interface, and the SATA SSD signal is sent to the SATA III interface, which must be connected to the motherboard's SATA interface via the SATA cable (included). These two are completely independent data channels. FCC and CE certified, highly reliable, stable PCIe X4 full speed: The speed of the M.2 NVMe SSD is unaffected and is the same as if it were installed on the motherboard. To reach full speed PCIe 4.0 X4 (64Gbps), the CPU, the motherboard's PCIe slot, and the PCIe M.2 SSD must all be PCIe 4.0 compatible. (Note: PCIe 4.0 is not supported on Intel CPUs of 11th generation or earlier.) Supports OS booting from M.2 NVMe SSD: Reinstall the OS and set up BIOS/UEFI booting from this M.2 NVMe SSD (Note: Some motherboards are too old to support OS booting. In this case, the M.2 NVMe SSD is used as a storage disk.) OS compatibility: Plug and play with Windows 11/10/8/Linux/Mac OS (Note: Windows 7 supports M.2 SATA SSDs but not M.2 NVMe SSDs). A new M.2 NVMe SSD must be initialized and formatted before it can be recognized by the computer's host.
