Description

Can I set up a RAID 1 Mirror after installing the operating system on a system configured in AHCI mode?

Resolution

Many systems have the SATA controller set to AHCI in the BIOS by default.  Before creating a RAID 1 volume the operating system will need to be reinstalled.

 

Note
  • Changing the SATA controller from AHCI to RAID/RST Premium will make the drive unbootable and could result in data corruption/loss.
  • Backup all data before proceeding.

 

To have a RAID-ready system, follow these steps:

  1. Confirm with the system vendor the platform supports Intel® RST.
  2. Enable RAID/RST Premium in system BIOS.
  3. Install the Intel® Rapid Storage Technology driver during Windows* OS installation.
  4. Install Intel® Optane™ Memory and Storage Management application from the Microsoft Store*.

To convert a RAID-ready system into a system with a two-drive RAID 1 volume, follow these steps:

  1. Install a second drive in the system.
  2. Boot Windows and open the Intel® Optane™ Memory and Storage Management software.
  3. Select Create Volume.
  4. Name the volume.
  5. Select Volume Type Real-time data protection (RAID 1) and then click Next.
  6. On the Create Volume screen:
    • Select the two installed disks.
    • Choose to keep data on the “System” disk.
    • Click Next.
  7. Review the warning screen and then click Create Volume.
  8. Confirm the RAID array is available on the Manage screen.
