I have an HP Z4 G4 workstation that I would like to set up RAID 1. I am using two M.2 SSDs. The service manual and spec sheet appears to indicate that the hardware RAID only works with SATA drives. There is an option in the BIOS to enable RAID for the M.2 drives, but there are not options to actually set up an array. I can't find anything definitive as to whether I can set up a RAID array using the two M.2 SSD drives. I have tried using the "Intel Rapid Storage Technology" program that came preinstalled with the unit. It shows the two drives, but only will let me select one when I try to create a new array. The other drive is grayed out. (I can choose either drive initially, but then the other drive goes gray and the next button will not highlight.) The help isn't of much use. All it says that if a feature is grayed out then that means you haven't selected all the prerequisites. There is no troubleshooting advice. My main question is does anyone know if the Z4 workstation supports RAID for the M.2 drives?
