You can now create MySQL, PostgreSQL, and Oracle RDS database instances with up to 6TB of storage and SQL Server RDS database instances with up to 4TB of storage when using the Provisioned IOPS and General Purpose (SSD) storage types. Existing MySQL, PostgreSQL, and Oracle RDS database instances can be scaled to these new database storage limits without any downtime.
Users of large transactional databases and data warehouses can now run even larger, higher performance workloads on a single database instance, without needing to shard the data across multiple RDS instances. The new storage limit doubles the available storage for MySQL, PostgreSQL, and Oracle databases on RDS, and quadruples the former limit for RDS SQL Server. SQL Server users can now also provision up to 20,000 input/output operations per second (IOPS), double the former limit of 10,000 IOPS.
