What are the implications of storing data in different R2 storage classes (e.g., Standard, Nearline, Coldline)?

R2 offers different storage classes designed for varying access patterns and cost requirements. Standard is for frequently accessed data and offers the lowest latency. Nearline is for data accessed less frequently, with slightly higher latency and lower storage costs. Coldline is for infrequently accessed data and has the highest latency but the lowest storage costs. Choosing the appropriate storage class optimizes both performance and cost.
