I booted my MacBook Pro into recovery mode and created a striped 0 RAID with two internal 500 GB hard drives. Then I went to reinstall high Sierra and went to the set up but when I went to click on the High Sierra drive it said can’t install high Sierra here because it’s part of an AppleRAID. I did also create a bootable USB recovery drive and it did not work from there either. How do I fix this?
I am curious as to why you would want to do that? I am having a problem understanding the benefit of such a configuration.

I really want to know I'm not being sarcastic nor recommending against it.
I wanted to create a striped RAID volume as doing so can speed up the performance of your computer rather than going out and buying expensive SSD whilst also combining both 500GB together so I get 1TB. I wanted a clean install of the OS and restoring from a backup can sometimes be sluggish when set up.
OK. Now I understand. So to improve performance a little. Doesn't a Raid 0 configuration increase the chance of data loss? If one of the drives fails you lose all your data. Please correct me if I'm wrong. I think I would opt for the SSD and an SSD external drive for backups rather than a Raid 0 configuration. I've never compared performance but I think an SSD will improve your performance more than a Raid 0 setup. But I may be mistaken.
You are right, it does increase data loss more because your data is spread through both drives but that also does increase read and right speeds. You are also right in saying that an SSD would increase it a lot more but I don’t need that big of a performance bump. I also do backup my computer daily to an external 4TB HDD.
I do not think you can. You need to boot the operating system before you can load the RAID drivers that understands how to read your stripped RAID 0
Unless of course you have a hardware RAID that always looks to macOS as a single volume.
Buy the SSD, any performance increase you might get from a stripped RAID will be minimal compared to what an SSD will do for your system. I've got a 2009 iMac with an SSD that works very well on High Sierra. It was just barely keeping up on Snow Leopard with rotating boot disk, and Snow Leopard is one of the most efficient and stable Mac OS X releases from 10 years ago. Every macOS release since then has just gotten more demanding.
Just get the SSD
So restoring did work. Install high Sierra or whatever operating system to one DRIVE and then back it up and go back into recovery mode. Then create the RAID and restore it. Thank you for all your help guys. 🥳😊
Good luck, keep us posted. :)
Were you able to select the top RAID, or just one if it's volumes?
I'd install it to an external drive then clone it to the RAID...
Carbon Copy Cloner...
Great. Best of luck. Thanks for the info.
i Basically installed macOS to a single HDD then backed it up and now I am restoring it to the RAID in recovery mode. It seems to be working. Fingers Crossed. 🤞🏼
Good work, great news, thanks. :)
How can i clean install high Sierra on RAID 0
