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

【2-in-1 M.2 SSD Adapter】: This adapter 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). NVMe SSD signals are sent directly to the PCIe x4 interface, while SATA SSD signals are sent to the SATA III interface and must be connected to the motherboard's SATA interface via a SATA cable (included). These two are completely independent data channels. FCC and CE certified, highly reliable, and 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 achieve the full speed of 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 from the 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). New M.2 NVMe SSDs must be initialized and formatted before they can be recognized by the computer's host. 【2-in-1 M.2 SSD Adapter】: This adapter allows you to install one M.2 NVMe SSD and one M.2 SATA SSD in your computer.
