With the RAID 0 striped set now available in the list of RAID arrays, it’s time to add members or slices to the set.
Add Slices to Your RAID 0 Striped Set
- Drag one of the hard drives from the left-hand pane of Disk Utility onto the RAID array name you created in the last step.
- Repeat the above step for each hard drive you wish to add to your RAID 0 striped set. A minimum of two slices, or hard drives, is required for a striped RAID. Adding more than two will further increase performance.
- Click the ‘Create’ button.
- A ‘Creating RAID’ warning sheet will drop down, reminding you that all data on the drives that make up the RAID array will be erased. Click ‘Create’ to continue.
Once you add all of the hard drives to the RAID 0 striped set, you are ready to create the finished RAID volume for your Mac to use.
During the creation of the RAID 0 striped set, Disk Utility will rename the individual volumes that make up the RAID set to RAID Slice; it will then create the actual RAID 0 striped set and mount it as a normal hard drive volume on your Mac’s desktop.
The total capacity of the RAID 0 striped set you create will be equal to the combined total space offered by all members of the set, minus some overhead for the RAID boot files and data structure.
You can now close Disk Utility and use your RAID 0 striped set as if it were any other disk volume on your Mac.
