Configuring SATA RAID 1 on ASUS Z270E

[EJ53]

I am building a new workstation using an ASUS Z270E Motherboard.

SATA Drive Configuration -

Port 0 - 275GB SSD

Port 5 - 1TB SSD
Port 6 - 1TB SSD

Running Windows 10 Professional on the 275GB SSD (Drive C)

My intention is to create a RAID 1 setup for Drive D, comprised of the two 1 TB SSD

I turn on RAID (EZ Tuning Wizard) and it shows all 3 drives as available storage, but when I attempt to setup RAID 1 (using the EZ Tuning Wizard) it selects the 275GB Drive and one of the 1 TB Drives and does not show the other drive.

I have installed Windows 10 on the C drive and it is working.

Does anyone know why I can't see the other 1 TB Drive or configure it as part of the RAID set?

Thank you

Make sure all the sata ports are enabled in the main bios. I was looking through your manual and some of them can be disabled (my Asus board has the same options).

They are all active as I can see the drives in Windows under Disk Manager, they are not formatted yet, but I can see them and I did see them in the BIOS both before and after switching on RAID. The problem is that I can only see the 275GB Drive (boot drive) and 1 of the 1 TB drives, under the RAID option and I'm not sure why

Could be a weird limitation of the software/firmware. Try putting your to-be raid drives in ports 0 and 1, and your boot drive in another port. Make necessary changes in bios for booting windows, then see if the raid bios likes that better.

Alternatively, you could probably configure your RAID array without having the boot drive connected at all.
