Hey Rydai thank you for your response. I'm getting some errors when trying to stripe the drives using RAID 0 from both disk utility and the command line.
Error: -69877: Couldn't open device --- command line error
and ""Disk erase failed with the error:
Couldn't open device disk 2" -- from disk utility.
Any thoughts? I've tried downloading the graid software but it isn't recognizing the drives unfortunately
