Windows Server Installation with Software RAID

Software RAID configuration on Windows Server is performed after the installation of the operating system using Disk Management Tools, so finish installing Windows Server before continuing with this guide.

Note: To perform RAID1 (Mirroring) requires 2 empty HDD, not including the HDD that already has the Windows OS installed on it.


Step 1: Open Windows Power Shell, type “diskmgmt.msc” (without quote marks) and press Enter to open up Disk Management Tools window.


Step 2: Delete any remaining data in the drives you wish to make into RAID drives.



Step 3: Right click on the unallocated space and choose the type of RAID to create. The naming of RAID in Windows is different from Linux:

RAID0: Spanned Volume

RAID1: Mirror Volume

Let’s go ahead and select “New Mirror Volume” (RAID1) for now.



Step 4: A wizard will popup. Click “Next” to continue.



Step 5: Select the disk(s) to be used for performing software RAID by highlighting them and click “Add >”. Then allocate the amount of space to be used as RAID partition. Click “Next” to continue.



Step 6: Choose “Assign the following drive letter” and pick a letter from the drop down list to represent the drive. Click “Next” to continue.



Step 7: Choose “Format this volume with the following settings” and fill in the details:

  • File system: NTFS
  • Allocation unit size: Default
  • Volume label: (Any Name)
  • Tick “Preform a quick format”

Click “Next”.



Step 8: Confirm the settings you have chosen from the list. Click “Finish” to continue.


A popup warning regarding conversion from basic disk(s) to dynamic disc(s) will appear. Ignore it and click “Yes” to continue.
