Note
1 These instances have a baseline bandwidth and can use a network I/O credit mechanism to burst beyond their baseline bandwidth on a best effort basis. Other instances types can sustain their maximum performance indefinitely. For more information, see instance network bandwidth.
2 These instances support enhanced networking using the Intel 82599 VF interface.
Amazon EBS specifications
The following table indicates which instance types are Amazon EBS optimized by default and which optionally support it. It also describes their EBS-optimized performance, including dedicated bandwidth to Amazon EBS, the typical maximum aggregate throughput that can be achieved on that dedicated connection with a streaming read workload and 128 KiB I/O size, and the maximum IOPS the instance type can support when using a 16 KiB I/O size. Instance types not listed do not support Amazon EBS optimization.
Important
An instance's EBS performance is bounded by the instance's performance limits, or the
aggregated performance of its attached volumes, whichever is smaller. To achieve maximum
EBS performance, an instance must have attached volumes that provide a combined performance
equal to or greater than the maximum instance performance. For example, to achieve
80,000 IOPS for r6i.16xlarge, the instance must have at least
5 gp3 volumes provisioned with 16,000 IOPS each
(5 volumes x 16,000 IOPS = 80,000 IOPS).
We recommend that you choose an EBS–optimized instance type that provides more dedicated Amazon EBS throughput than your application needs; otherwise, the connection between Amazon EBS and Amazon EC2 can become a performance bottleneck.

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.
