 ## Input/Output Operations
 
-Input/output operations per second (IOPS) are a relatively low-level unit in AWS for measuring disk performance. The maximum size of an IOP is 256 KiB for SSD volumes and 1 GiB for HDD volumes. 1 GiB of storage is worth 3 IOPS, so a 1,000 GiB EBS Volume has 3,000 IOPS available. When using these volume types you are charged for the amount of provisioned IOPS even if you don't fully utilize them.
