SAA-C03 - Design High-Performing Architectures - Section 3.2

Select high-performing block storage by choosing appropriate Amazon EBS volume types for IOPS and throughput needs.

Describe the Amazon EBS volume types - gp3, io2, st1, sc1 - and match each to its performance profile of IOPS ceiling, throughput ceiling, and cost characteristics. Choose Provisioned IOPS io2 volumes for latency-sensitive transactional databases that require consistent sub-millisecond performance, and Throughput Optimised HDD st1 for sequential big-data workloads where cost per GB matters more than IOPS.
