EBS disk volume type configuration options

Depending on your workload, you have multiple EBS disk volume types available that allow you to optimize storage performance and cost for a broad range of applications.

These volume types are divided into two broad categories as described below:

SSD-backed storage for transactional workloads
- gp3: General-purpose SSD
- Clusters can store up to 1.5PB (raw) SSD in AWS
HDD-backed storage for throughput-intensive workloads
- st1: Streaming-optimized hard drive
