iops

The target IOPS rate of the volume. This parameter is valid only for gp3, io1, and io2 volumes.

The following are the supported values for each volume type:

• gp3: 3,000 - 16,000 IOPS

• io1: 100 - 64,000 IOPS

• io2: 100 - 256,000 IOPS

For io2 volumes, you can achieve up to 256,000 IOPS on instances built on the Nitro System. On other instances, you can achieve performance up to 32,000 IOPS.

Default: The existing value is retained if you keep the same volume type. If you change the volume type to io1, io2, or gp3, the default is 3,000.
