AWS Certified Solutions Architect Associate SAA-C03 Practice Question

For frequent read and write operations where latency is not a primary concern, HDD volume types like Throughput Optimized HDD (st1) are a cost-effective solution. They offer a lower price point compared to SSD-based options while still providing adequate throughput for the described workload. General Purpose SSD (gp2) is more expensive and is optimized for a balance of performance and cost. Provisioned IOPS SSD (io1/io2) offers the highest level of performance for IOPS-intensive workloads, which is not required in this scenario and would be unnecessarily costly. Cold HDD (sc1) volumes are designed for infrequent access, and using them for frequent operations would lead to suboptimal performance.
