M.2 NVMe SSD PCIe X4 Full Speed Adapter: With this PCIe X4 adapter, M.2 PCIe SSD can operate at PCIe X4 full speed. It's like being installed directly on the motherboard, and the speed is basically unaffected.
No Capacity Limitation: Support 2T/4T capacity M.2 PCIe (NVMe/AHCI) SSD, Support 2230/2242/2260/2280/22110 size
Work with PCIe 4.0/3.0 M.2 SSD, not Support M.2 NGFF SATA SSD: To reach PCIe 4.0 X4 (64Gbps) full speed, CPU, and motherboard PCIe slot and M.2 PCIe SSD should all be PCIe 4.0 feature. (Noted: Intel 11th Gen and above CPU support PCIe 4.0)
Support OS booting from PCIe SSD: Need to reinstall OS, and set up BIOS/UEFI booting from this M.2 PCIe SSD. (Noted: Some motherboards are too old to set up OS booting from M.2 PCIe SSD. Additionally, Windows 7 may not support OS booting from M.2 PCIe SSD. In this case, M.2 PCIe SSD can be used as a storage disk)
M.2 PCIe SSD as Storage Disk: Brand new M.2 PCIe SSD needs to be Initialized and formatted before the PC host recognizes it.
