This adapter card can switch out 2 SATA interfaces through the M.2 (A+E Key) slot of the PC host, and the user can connect 2 SSD solid state drives or mechanical hard drives with SATA interfaces at the same time through the SATA data cable. Adopting the super PCIe 3.0 bus bandwidth, the data transmission speed is much faster than PCIe 2.0. It is widely used in PC computers, servers, industrial computers, consumer electronic devices, and storage devices.
