Amazon EBS Volume Types

Solid State Drive (SSD) Volumes

SSD-backed volumes are optimized for transactional workloads involving small, frequent writes and reads. They offer high performance, low latency, and high IOPS (Input/Output Operations Per Second). SSD volumes are typically used for applications that require fast and consistent access to data, such as databases, online transaction processing (OLTP) systems, and web servers.

Magnetic Volumes

Magnetic volumes, formerly known as Standard volumes, provide the lowest cost per gigabyte of storage. They are suitable for workloads that involve large sequential reads and writes, such as data warehousing, backup and recovery, and media storage. Magnetic volumes are not as fast as SSD volumes, but they offer a good balance of performance and cost.

Magnetic Storage

Magnetic Storage, formerly known as RDS Standard storage, is a good match for small databases, development and test environments, and infrequently accessed data. It is the most cost-effective storage option for workloads that do not require high performance or low latency.

Pricing

With Amazon EBS, you pay only for what you provision. The pricing for Amazon EBS volumes is listed below:

• SSD volumes: $0.04 per GB-month
• Magnetic volumes: $0.025 per GB-month
• Magnetic Storage: $0.01 per GB-month

Conclusion

Amazon EBS provides a range of volume types to meet the needs of different workloads and budgets. SSD volumes offer the highest performance and lowest latency, but they come at a higher cost. Magnetic volumes are more cost-effective, but they offer lower performance. Magnetic Storage is the most cost-effective option, but it is not suitable for workloads that require high performance or low latency. When choosing an EBS volume type, you should consider the performance, cost, and durability requirements of your workload.
