Today, AWS announces the availability of next-generation Provisioned IOPS (PIOPS) io2 Block Express storage volumes for Amazon Relational Database Service (Amazon RDS). Amazon RDS io2 Block Express volumes provide consistent sub-millisecond latency for mission critical workloads.

Amazon RDS io2 Block Express volumes are designed for all your critical database workloads that demand high performance, high throughput, and consistently low latency. io2 Block Express storage has the lowest p99.9 I/O latency and the best outlier latency control among major cloud providers, making it ideal for the most I/O-intensive, mission-critical database workloads. io2 Block Express supports 99.999% durability, up to 64 TiB volumes, 4,000 MB/s throughput, and up to 256,000 Provisioned IOPS for your most demanding database needs for the same price as Amazon RDS io1 volumes. You can upgrade from an Amazon RDS io1 volume to an Amazon RDS io2 Block Express without any downtime using the ModifyDBInstance API.

California), US West (Oregon), Asia Pacific (Hong Kong), Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Canada (Central), Europe (Frankfurt), Europe (Ireland), Europe (London), Europe (Stockholm), Middle East (Bahrain) Regions and supports Amazon RDS for PostgreSQL, RDS for MySQL, RDS for MariaDB, RDS for SQL Server, RDS for Oracle, RDS for Db2, RDS Custom for SQL Server, and RDS Custom for Oracle.
