Note

1 These instances can support maximum performance for 30 minutes at least once every 24 hours, after which they revert to their baseline performance. Other instances can sustain the maximum performance indefinitely. If your workload requires sustained maximum performance for longer than 30 minutes, use one of these instances.

2 default indicates that instances are enabled for EBS optimization by default. supported indicates that instances can optionally be enabled for EBS optimization For more information, see Amazon EBS–optimized instances.
