Balanced Performance
The Balanced performance level provides a good balance between performance and cost savings for most workloads, including those that perform random I/O such as boot volumes.
This option provides linear peformance scaling with 60 IOPS/GB up to 25,000 IOPS per volume. Throughput scales at 480 KB/s/GB up to a maximum of 480 MB/s per volume.
See Performance Details for Instance Shapes for performance characteristics and instance details for Compute shapes.
Volume Size and Performance
The following table lists the Block Volume service's throughput and IOPS performance numbers based on volume size for this option. IOPS and KB/s performance scales linearly per GB volume size up to the service maximums so you can predictably calculate the performance numbers for a specific volume size. If you're trying to achieve certain performance targets for volumes configured to use the Balanced performance level you can provision a minimum volume size using this table as a reference.
