M.2 NGFF PCI-E LANE SSD to PCIE X4&3.0 to SATA Adapter Card

PCI-E NGFF （M.2 M KEY SSD） SSD has to connect to PC with PCI-EX4, X8, or X16 port. Make sure your PC has the ports.
After connection by PCI-EX4, X8, or X16 port with PC , PCI-E NGFF SSD can be recognized by operation system. The general computer can't read it in BIOS. Hence it doesn't support system setup.
In our testing, Z77 (Win7, Win8) can recognize the SSD and finish Partition after installation. However, it can't find the SSD after the system files copying and restart PC.  The reason should be most of the previous BIOS can't support PCI-E device restarting.   It's not the issue of the card itself.
M.2 B KEY SSD can work as general drive if it was connected to PC via Sata data cable
