iops
The number of I/O operations per second (IOPS). For gp3
, io1
, and io2
volumes, this represents the number of IOPS that are provisioned for the volume. For gp2
volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.
The following are the supported values for each volume type:
gp3
: 3,000 - 16,000 IOPSio1
: 100 - 64,000 IOPSio2
: 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.
This parameter is supported for io1
, io2
, and gp3
volumes only.
