With io2 Block Express, customers can get the highest performance block storage in the cloud with 4x higher throughput, IOPS, and capacity than io2 volumes at no additional cost. But some customers want even lower latency and want to go beyond current single volume performance. To learn more about pricing, visit the Amazon EBS pricing page.Ĭustomers choose io2 volumes to run their critical, performance-intensive applications. These volumes also support Multi-Attach, which allows customers to attach an io2 or io1 volume to up to sixteen Nitro-based EC2 instances within the same Availability Zone. For applications that have less stringent performance or durability requirements, we recommend evaluating general purpose volumes.
This makes io2 volumes ideal for performance intensive, business-critical applications such as SAP HANA, Oracle, Microsoft SQL Server, and IBM DB2 that will benefit from higher uptime. Furthermore, when attached to EBS-optimized EC2 instances, io2 volumes are designed to achieve single-digit millisecond latencies and deliver the provisioned performance 99.9% of the time. io2 volumes are also designed to provide 100X higher durability of 99.999% as well as a 10X higher IOPS to storage ratio of 500 IOPS for every provisioned GB – at the same price as io1. Io2 volumes, available since 2020, are designed to deliver up to a maximum of 64,000 IOPS and 1,000 MB/s of throughput per volume, 4x more IOPS than general-purpose volumes. Provisioned IOPS volumes, backed by solid-state drives (SSDs), are the highest performance Elastic Block Store (EBS) storage volumes designed for your critical, IOPS-intensive and throughput-intensive workloads that require low latency.
