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 - 80,000 IOPS

• io1: 100 - 64,000 IOPS

• io2: 100 - 256,000 IOPS

Instances built on the Nitro System can support up to 256,000 IOPS. Other instances can support 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.
