Amazon EBS io2 Block Express supports all commercial and AWS GovCloud (US) Regions

Amazon EBS io2 Block Express volumes are now available in all commercial and AWS GovCloud (US) Regions, except China regions.

io2 Block Express leverage the latest generation of EBS storage server architecture designed to deliver consistent sub-millisecond latency and 99.999% durability. With a single io2 Block Express volume, you can achieve 256,000 IOPS, 4GiB/s throughput, and 64TiB storage capacity. You can also attach an io2 Block Express volume to multiple instances in the same Availability Zone, supporting shared storage fencing through NVMe reservations for improved application availability and scalability. With the lowest p99.9 I/O latency among major cloud providers, io2 Block Express is the ideal choice for the most I/O-intensive, mission-critical deployments such as SAP HANA, Oracle, SQL Server, and IBM DB2.

Customers using io1 volumes can upgrade to io2 Block Express without any downtime using the ModifyVolume API to achieve 100x durability, consistent sub-millisecond latency, and significantly higher performance at the same or lower cost than io1. With io2 Block Express, you can drive up to 4x IOPS and 4x throughput at the same storage price as io1, and up to 50% cheaper IOPS cost for volumes over 32,000 IOPS. You can use AWS Compute Optimizer and AWS Cost Optimization Hub to recommend the optimal io2 volume performance required by your workloads, based on the io1 utilization data collected by Amazon CloudWatch.

You can create and manage io2 Block Express volumes using the AWS Management Console, the AWS CLI, or the AWS SDKs. For more information on io2 Block Express, see our product overview page.
