I bought this Corsair NVMe drive with an Asus Crosshair VIII Hero motherboard. It works well in Gen3 PCIe x4 mode. It works well in Gen4 PCIe x2 mode. It does not work in Gen4 PCIe x4 mode. Corsair's solution is to either update the firmware (which is undesirable) or perform a secure erase until all four tracks are used up. This is unacceptable. I may have to return this product to Revain as it may not work as advertised.
