GLOTRENDS Dual M.2 Adapter for One M.2 NVMe SSD and One M.2 SATA SSD, Support PCIe 4.0/3.0 Full Speed (PA12)

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.
It is FCC and CE certified, ensuring highly reliable and stable PCIe X4 full speed. Your M.2 NVMe SSD speed remains unaffected, just as if it was installed on the motherboard.
To reach PCIe 4.0 X4 (64Gbps) full speed, the CPU and motherboard PCIe slot and M.2 NVMe SSD should all be PCIe 4.0 features (Note: PCIe 4.0 is not supported on Intel CPUs below 11th generation)
Support OS booting from the M.2 NVMe SSD. Please reinstall OS and set up BIOS/UEFI boot from this M.2 NVMe SSD. (Note: Some motherboards are too old to support OS booting. In this case, M.2 NVMe SSDs can be used as storage disks)
OS compatibility: Plug-and-play in Windows 11/10/8/Linux/Mac OS (Note: Windows 7 supports M.2 SATA SSD, but no M.2 NVMe SSD). The new M.2 NVMe SSD needs to be initialized and formatted before it can be recognized by the computer host.
