Which Amazon Elastic Block Store (Amazon EBS) volume type will meet these requirements MOST cost-effectively?

Explanations:

GP2 volumes provide a baseline performance of 3 IOPS per GB, with a maximum of 16,000 IOPS. However, the performance is tied to the storage capacity, meaning the company may not be able to provision disk performance independently of storage capacity, which does not fully meet the requirement.

io2 volumes are designed for high performance and durability, offering up to 64,000 IOPS per volume, but they are more expensive than the GP3 option. The requirement for cost-effectiveness suggests that io2 may not be the best choice despite its performance capabilities.

GP3 volumes allow users to provision IOPS independently from storage capacity, enabling the company to achieve up to 16,000 IOPS for a lower cost than io2 or io1. This makes GP3 the most cost-effective choice for the company’s requirements.

io1 volumes also provide the ability to provision IOPS independently of capacity, but they are generally more expensive than GP3. Since the company seeks cost-effectiveness and their peak IOPS requirement is well within the capabilities of GP3, io1 is not the optimal choice.
