Today, we are announcing an improvement to the Amazon Elastic Block Store (EBS) performance of Amazon Compute-Optimized C6in, General Purpose M6in and M6idn, and Memory-Optimized R6in and R6idn EC2 instance types.

EC2 C6in, M6in, M6idn, R6in, and R6idn are sixth-generation network optimized instances powered by 3rd generation Intel Xeon processors, and offer the highest EBS performance across EC2 instances. These instances are built on the AWS Nitro System that enables your instances to deliver higher overall performance. With the latest enhancements to the AWS Nitro System, we have increased the maximum EBS performance on these instances across all instance sizes, up to 100 Gbps of EBS-optimized bandwidth and 400,000 IOPS on the largest 32xlarge and metal sizes. The large to 4xlarge instance sizes can now support burst performance of up to 25Gbps EBS-optimized bandwidth and 100,000 IOPS. With improved EBS performance, these instances are an ideal fit for SQL and NoSQL databases, high performance file systems, in-memory databases, and real-time big data analytics. This performance increase also provides an opportunity to use smaller instance sizes to save costs while still meeting performance requirements.

All existing and new C6in, M6in, M6idn, R6in, and R6idn instances launched starting today will benefit from this performance increase at no additional cost. For running instances, you can simply stop and start your instances to enable this performance increase. The higher EBS performance is available in all AWS regions where these instance types are generally available today. Please visit the EBS-optimized instance page for more details.
