Today, AWS announced the availability of next-generation General Purpose gp3 storage volumes for Amazon Relational Database Service (Amazon RDS). Amazon RDS gp3 volumes gives you the flexibility to provision storage performance independently of storage capacity, paying only for the resources you need. Every gp3 volume provides you the ability to select from 20 GiB to 64 TiB of storage capacity, with a baseline storage performance of 3,000 IOPS included with the price of storage. For workloads that need even more performance, you can scale up to 64,000 IOPS for an additional cost.
