macOS Sierra saw the return of RAID support to Apple’s Disk Utility, a feature that was removed when OS X El Capitan first came on the scene. With the return of RAID support in Disk Utility, you no longer need to resort to using Terminal to create and administer your RAID systems.

Of course, Apple couldn’t just return RAID support to Disk Utility. It had to change the user interface just enough to ensure that your previous method of working with RAID arrays would be different enough to require learning a few new tricks.

That would be fine if Apple had upgraded the RAID utility to include new capabilities, but as far as I can tell, no updates, either to basic functions or to the RAID driver, are present in the latest version.

RAID 0, 1, 10, and JBOD

Disk Utility can still be used to create and manage the same four RAID versions it has always been capable of working with: RAID 0 (Striped)RAID 1 (Mirrored)RAID 10 (Mirrored set of Striped drives), and JBOD (Just a Bunch Of Disks).

In this guide, we’re going to look at using Disk Utility in macOS Sierra and later to create and manage these four popular RAID types. There are, of course, other RAID types you can create, and third-party RAID apps that can manage RAID arrays for you; in some cases, they can even do a better job.

If you need a more advanced RAID utility, I suggest either SoftRAID, or a dedicated hardware RAID system built into an external enclosure.
