Hi [NAME] thank you for sharing update.  The intelligent system already knows that a single 2TB (C:) boot drive has been installed. There is no requirement to change the BIOS RAID_0 array setting. As part of your disaster Recovery Plan, please use Macrium Software | Reflect Free Edition to create a single 2TB standby boot drive clone (copy), that can be swapped in if the original single 2TB SSD boot drive becomes irrecoverable.  If the original 2 x 1TB dual boot drive is reinstated, the system will automatically function as a 2TB (C:) RAID_0 array. There is no requirement to change the BIOS RAID_0 array setting.  Install the blank M.2 2TB SSD card into the second slot, power on and open Disk Management, right click on new blank SSD to format and assign a permanent letter so that windows can see and use new drive.

I have an x17 R1 with 2x1TB SSD as Raid 0. I need to upgrade the storage as its becoming too full. I hope to install 1 single 2TB SSD as system disk and restore the current system to that. Then either use one of the original SSD in slot 2 to make 3TB total or add a 2nd 2TB SSD but keeping non-raid setup in either case. What I am not sure about is after backing up the existing Raid 0 disk (using Macrium Reflect Free) and Disk image backup, can I then simply restore this to the 2TB SSD once installed. I realize I need to change the Bios to turn raid off, after removing the current drives. If this doesn't work, will I simply be able to turn Raid back on and reinstall the original drives?
