How to Create or Delete a RAID Using Apple Disk Utility
Here’s how to create or delete a RAID 0 or RAID 1 multi-disk storage system using Apple Disk Utility.
NOTE: Here’s a tutorial that explains what these RAID levels mean.
Disk Utility is a Mac application that is stored in Applications > Utilities. Disk Utility can only create RAID 0 and RAID 1 volumes. You’ll need to use other software, such as SoftRAID from OWC, to create RAID 4, 5, 6, or 1+0.
TO CREATE A RAID
- To create a RAID, open Disk Utility and choose File > RAID Assistant.
- Select the type of RAID you want to create. (RAID 1 should only be used for 2-drive systems and generally not for SSDs.)
- Select the drives you want to include in the RAID. Here I included all the blades in a four-blade OWC Thunderblade.
- Specify the name, format and chunk size of the RAID.
- This screen illustrates my recommendations.
Click Next and, after a few seconds, the RAID is created and displayed on the desktop.
TO DELETE A RAID
To delete a RAID, first, unmount it from the Desktop.
NOTE: Even though the RAID is unmounted, Disk Utility will still display it. If it doesn’t, make sure the RAID is turned on and connected to your Mac.
- Select the RAID’s name in the RAID Sets section at the bottom of the sidebar.
- Click the Delete RAID button on the right.
- After a few seconds, the RAID will be gone.
- Creating or deleting a RAID destroys any data currently recorded on the drives in the RAID.
- Once a RAID is created, it can’t be modified, without first deleting it and creating a new one.
