Which EBS volume type allows to increase IOPS performance without increasing the provisioned capacity?

(1) gp3

(2) io1

(3) io2/io2 Block Express

Explanation

• gp3, io1, and io2/io2 Block Express EBS volume types include a performance option to increase the IOPS performance without increasing the provisioned volume capacity. IOPS performance provisioning is subject to minimum IOPS-to-capacity ratios per volume type.
• gp3 EBS volume type also includes the capability to change the throughput performance without increasing the provisioned volume capacity. Throughput performance provisioning is subject to a minimum throughput-to-IOPS performance ratio.
• gp2, st1, and sc1 EBS volume types scale performance by increasing provisioned capacity.
