The Raspberry Pi compute module 4 has a PCIe x1 slot.  You could run a
SATA multiport controller with that.  Or a stronger USB
multi-controller card.

As a general note, if you leave the raid on the very slow I/O I am
concerned about array rebuild time if you ever have to replace a
disk.  How long does a scrub take you?
