RAID 0 is a popular disk setup solution to achieve the fastest possible read and write disk speeds by splitting data between two or more hard drives. The latest version of Mac OS X High Sierra (10.13) does not allow you to simply install to any kind of RAID configuration. This has frustrated a lot of the Mac community. Until Mac OS X High Sierra officially supports RAID configurations, follow the steps below to setup a fully functional RAID 0 configuration.
Nov 24, 2015 Even though the GUI method for creating RAID volumes is now gone in OS X El Capitan, you can still access the basic underlying technology in OS X to perform most functions: appleRAID. Part of the diskutil command, appleRAID can be used to create and manage RAID 0 (striped), RAID 1 (mirrored), and JBOD (concatenated) volumes. A hardware RAID is a separate computer that runs the RAID. You connect the RAID box to your Mac, install software that lets OS X talk to the box, and you’re off and running. A software RAID is one. Up to10%cash back Now, you can easily convert your existing Apple RAID stripe (RAID 0) and mirror (RAID 1) volumes to SoftRAID volumes and preserve all the files on those volumes. Additionally, you can convert a standard Apple RAID stripe (RAID 0) and mirror (RAID 1) volume to a RAID 1+0, which continues to function after a disk fails. RAID is often managed by a hardware solution (an add-on card in a high-end system) but this solution is unnecessary with Mac OS X's built-in software RAID option. The procedure for setting up software RAID assumes that you have installed at least two separate disks in the system, in addition to the startup disk.

In order to install the latest version of Mac OS X onto a RAID 0 slice, you must clone a copy of your Mac OS X installation straight to the RAID 0 drives (not a restore, such as Time Machine, which will not work). To accomplish this, you need an external hard drive and a copy of SuperDupersoftware in addition to your RAID 0 drives. We will use the same Mac machine (that will use RAID 0) to perform all the steps below. Logitech usb unifying software mac instructions. This method uses hardware RAID and is not a software RAID.
Note: We strongly recommend taking a full backup (Time Machine) to another drive just in case when performing these steps! Save yourself from an accident!
Note: Be sure to complete your SuperDuper clones on the same type of Mac you will install the RAID 0 configuration on. This is important because your Mac OS High Sierra clone will have drivers and system files specific to that machines hardware.
Open Disk Utility in Applications -> Utilities and create your RAID 0 array shown below.
Go to File -> RAID Assistant

Select your 2 internal hard drives to create the RAID array from
Name your single RAID drive. For Chunksize, choose a lower size if you will be using the RAID for regular needs (email/browsing/word processing.) For video editing, choose a higher chunk size.

The copy will complete successfully. Finally, go to System Preferences -> Startup Disk and select your new drive and restart. The first restart may take a little time as your boot files load for the first time.
