Provisioned IOPS SSD is an EBS storage type for workloads that need predictable, high read and write performance. Unlike general-purpose SSD, it lets you provision IOPS directly rather than relying mainly on a moderate baseline with bursting. section 8.1.3 section 10.6.1
Choose this storage when the workload requires:
- Guaranteed high throughput for large, business-critical databases. section 8.1.3
- Production database storage with more predictable read and write performance than general-purpose SSD. section 10.6.1
- A volume and EC2 instance whose capabilities are balanced; the instance network connection can limit effective EBS bandwidth. section 8.1.3 section 8.3
RDS production database
For an RDS database whose read and write throughput must remain predictable, select Provisioned IOPS SSD instead of general-purpose SSD. General-purpose SSD is suitable when moderate baseline performance and bursting are sufficient; magnetic storage favors low cost and less predictable access. section 10.6.1
