If you mean setting up RAID for USB connected external hard drives, then this is a feature that has not yet been implemented. But the good news is that it has been included in our roadmap, and yes, in the future, ZimaOS will provide RAID support for USB connected hard drives.
If you are experiencing issues with RAID for internal hard drives such as SATA, please provide us with your connection method and a screen recording of the setup process so we can help you better locate and resolve the issue.
Looking forward to your reply.
