RDS Oracle storage redundancy

Question

Is the General Purpose (SSD) storage for RDS Oracle redundant in the same way that Aurora is?  
  
The product page for Amazon Aurora states it features a distributed, fault-tolerant, self-healing storage system. I've read in a few places this means 6 copies across 3 AZ's. But can't find anything stating the same for Oracle storage.  
  
I'm after confirmation that the storage for a single AZ Oracle instance is redundant with multiple copies across multiple AZs, or do I need to look at multi AZ configuration?

Answer

RDS for Oracle (and the other non-Aurora engines) uses EBS for its storage, providing redundancy _within_ an AZ. To obtain redundancy across AZs you need to use Multi-AZ.

Answer

Amazon Aurora stores data in 3 AZs by default.

For Amazon RDS we would need to use Multi-AZ  feature.
