This adapter card can switch out 2 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 interfaces at the same time through the data cable. Adopting the super PCIe 3.0 bus bandwidth, the data mission speed is much faster than PCIe 2.0. It is widely used in PC computers, servers, industrial computers, consumer electronic devices, and storage devices. Committed to bringing users and players faster, lower power consumption, high reliability and high performance storage solutions. 1. KEY A/E Riser Board. 2. Support NGFF (M.2) 2230 key A/E. 3.
