A common problem would be throughput though. Storage capacity scales much faster than access speed. If you are storing an item only 3 times and lets say each storage location gives you 50,000 IOPS max then you can only ever service 150,000 IOPS of this item which might not be enough.

Vast majority of data rarely (if ever) gets read so you use a cache for that
