| Volume type | Capacity | Included performance | Extra IOPS | Good fit |
|---|---|---|---|---|
| gp3 | $0.08 per GB-month | 3,000 IOPS and 125 MB/s baseline, regardless of size | $0.005 per provisioned IOPS-month above 3,000; extra throughput $0.04 per MB/s-month above 125 | Most small and medium databases |
| io2 Block Express | $0.125 per GB-month | None; every IOPS is provisioned and billed | Tiered: $0.065 up to 32,000; $0.0455 for 32,001–64,000; $0.032 above 64,000 (per IOPS-month) | Large, I/O-heavy databases that need consistent high IOPS on one volume |
