For each DB Instance class, what is the maximum size of associated storage capacity?
“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.”
