How to Create a Software RAID-0
See the RAID-0 striping page for a discussion.
Creating a software RAID-0 stripe in Disk Utility
Here, is created 2-drive RAID-0 stripe volume Master of capacity 8TB:
- Click the tab .
- Enter a
Leave the file system as .
and choose choose .
- Drag the desired drive icons at left (“4TB HGST....”) into the area at right (“New member: ...”).
- Click .
It is possible to make a RAID out of partitions on each drive. First partition each drive identically, then follow the steps above for each RAID set.
Confirm the change. This will erase everything on the drives chosen, so be sure the correct drives have been chosen (risks of making a mistake go up with 4/6/10 drives!). The result is one 8TB volume consisting of two 4TB hard drives.
When done, observe that the two hard drives are shown now withunder each, and that the RAID itself is listed as , with volume under it. This confusing display has been present in Disk Utility for many years.
Creating a software RAID-0 stripe in SoftRAID
In this example, a 4-drive RAID-0 striped volume Master of capacity 4TB is created using four 4TB drives.
As shown, 1TB is used from each 4TB drive to create a 4TB volume; that leaves 3TB unused on each drive for other purposes (another RAID volume, or independent volumes, or simply unused).
- Choose .
- Enter a name in the text box.
- Select the drives to be used.
- Click .
The result here is one 4TB volume consisting of four 4TB hard drives, using 1TB from each drive. Repeat the steps above to create additional volume(s), which could be any type of RAID.
