Amazon EBS io2 Block Express offers the highest performance block storage in the cloud with 4x higher throughput, IOPS, and capacity than gp3 volumes, along with sub-millisecond latency. Block Express is the latest generation of Amazon EBS storage server architecture purpose-built to meet the performance and latency requirements of the most demanding applications. io2 Block Express is designed to provide 4,000 MB/s throughput per volume, 256,000 IOPS/volume, up to 64 TiB storage capacity, and 1,000 IOPS per GB as well as 99.999% durability, making it ideal for your largest, most I/O intensive, mission-critical deployments of Oracle, SAP HANA, Microsoft SQL Server, and SAS Analytics.
io2 Block Express is available on all Nitro-based EC2 instances. For more information, see io2 Block Express documentation.
