The relational model is the best known form for representing and manipulating data.

Where the physical data were stored (RAM or hard disk) is irrelevant for that.

The relational model was not designed for hard disks nor RAM. It is a logical model.

Performance and the relational model are independent. A main memory relational DBMS may perform as fast as any kind of main memory DBMS.

And performance is not the unique issue.
