Any kind of RAID over USB is not supported and is, in general, a very bad idea. USB interfaces can filter drive ATA commands and there's the issue of equal bandwidth for the array's member drives which (without equal bandwidth) can prevent the array from assembling. While RAID over USB may work, it may suddenly stop working without notice or reason. It's a recipe for data loss.

If you want a "RAID like" array, with drives aggregated under a common mount point, consider UnionFS+SNAPRAID. (Both are OMV plugin's) This setup protects against drive failure, bitrot, provides file backup and restore functions, and it will work much better over USB. It's very flexible.
I like the storage to be expandable and failure tolerant. Also want to avoid bitrod

Keep in mind that M4 is prone to undervoltage. You need a PSU that is capable of holding 5.xV under load and a very short USB-C cable with thick power wires.
