This can be done by connecting a Pegasus32 R4 ideally of the same capacity. Connect the Pegasus32 R4 to the Mac Pro and follow these steps.
Note: Both the Pegasus R4i MPX module and the Pegasus32 R4 can be stripped together using the macOS disk utility. Follow these simple steps:
Step 1. Please be sure to create a logical drive on the Pegasus32 R4 and Pegasus R4i. Please use the Promise utility to determine if you them created. Please see link to download the latest Promise utility.
Step 2. Once you have the logical drives created. Open Disk utility --> file --> Raid Assistance
Select RAID type
Select the volumes created via the R4i and Pegasus32 R4 *NOTE Pic below is using 4 drives from an 8bay Pegasas32 R8. The Pegasus32 R8 is the 8bay version of the Pegasus32 R4.
Select your stripe size, name the stripe volume.
Your done.
Once the RAID stripe is created we benchmarked.
