The ability to scale and optimize data storage for maximum performance is among its most crucial features. A data storage system is said to be scalable if it can accommodate growing volumes of data and requests without sacrificing its performance, dependability, or quality. Performance optimization is the process of enhancing a data storage system's efficacy and efficiency by lowering latency, raising throughput, and using fewer resources.

In the view of above statement, discuss about key factors and techniques that influence scalability and performance optimization in data storage. In the discussion, you could include necessary diagrams, real$-$world statistics with proper citation and reference.
