At AWS re:Invent 2020, we previewed Amazon EBS io2 Block Express volumes, the next-generation server storage architecture that delivers the first SAN built for the cloud. Block Express is designed to meet the requirements of the largest, most I/O-intensive, mission-critical deployments of Microsoft SQL Server, Oracle, SAP HANA, and SAS Analytics on AWS.

Today, I am happy to announce the general availability of Amazon EBS io2 Block Express volumes, with Amazon EC2 R5b instances powered by the AWS Nitro System to provide the best network-attached storage performance available on EC2. The io2 Block Express volumes now also support io2 features such as Multi-Attach and Elastic Volumes.

In the past, customers had to stripe multiple volumes together in order go beyond single-volume performance. Today, io2 volumes can meet the needs of mission-critical performance-intensive applications without striping and the management overhead that comes along with it. With io2 Block Express, customers can get the highest performance block storage in the cloud with four times higher throughput, IOPS, and capacity than io2 volumes with sub-millisecond latency, at no additional cost.

* The throughput limit is between 128 MiB/s and 250 MiB/s, depending on the volume size. ** Maximum IOPS and throughput are guaranteed only on instances built on the Nitro System provisioned with more than 32,000 IOPS.
