You need to provision a single EBS volume that is 500 GiB in size and needs to support 20,000 IOPS. Which EBS volume type will you select?
Provisioned IOPS SSD supports up to 50 IOPS per GiB with up to 32,000 IOPS per volume
General purpose SSD supports 3 IOPS per GiB and can burst up to 3000 IOPS (volumes > 334GB), and a maximum of 16,000 per volume
The HDD options provide much lower IOPS per volume (500, 250)
