Increased network-attached storage limits for AWS Postgres databases

January 14, 2026

We've increased the maximum limits for AWS Postgres databases using network-attached storage (EBS).

You can now configure your database storage with:

• 64 TiB maximum size (up from 16 TiB)
• 80,000 IOPS (up from 16,000)
• 2,000 MiB/s throughput (up from 1,000 MiB/s)

These higher limits give you more flexibility to scale your database storage and performance as your workload grows.

See Cluster Storage for more information on configuring storage settings.
