EBS Volume Types

• EBS provides the following volume types
  • Solid State Drives (SSD)
    • Categories
      • General Purpose SSD: Provides a balance of price and performance
        • Volume Types:
          • gp2:
            • Max Throughput per volume: 250 MiB/s
          • gp3:
            • Max Throughput per volume: 1000 MiB/s
        • Durability: 99.8%-99.9% (0.1 – 0.2% of annual failure rate)
        • Use cases:
          • Low-latency interactive apps
          • Development and Test Environments
        • Volume Size: 1 GiB – 16 TiB
        • Max IOPS per volume: 16,000
      • Provisioned IOPS SSD: Provides high performance for mission-critical, low-latency or high throughput workloads
        • Volume Types:
          • io1:
            • Durability: 99.8%-99.9% (0.1 – 0.2% of annual failure rate)
            • Usecases:
              • Workloads that require sustained IOPS performance or more than 16,000 IOPS
              • I/O-intensive Database Workload
            • Volume Size: 4 GiB – 16 TiB
            • Max IOPS per volume: 64,000
            • Max Throughput per volume: 1000 MiB/s
          • io2:
            • Durability: 99.999% (0.001 of annual failure rate)
            • Usecases:
              • Workloads that require sustained IOPS performance or more than 16,000 IOPS
              • I/O-intensive Database Workload
            • Volume Size: 4 GiB – 16 TiB
            • Max IOPS per volume: 64,000
            • Max Throughput per volume: 1000 MiB/s
          • io2 Block Express:
            • Durability: 99.999% (0.001 of annual failure rate)
            • Usecases:
              • Workloads that require
                • Sub-millisecond latency
                • Sustained IOPS performance
                • More than 64000 IOPS or 1000 MiB/s Throughput
            • Volume Size: 4 GiB – 64 TiB
            • Max IOPS per volume: 2,56,000
            • Max Throughput per volume: 4000 MiB/s
  • Hard disk Drives (HDDs)
    • Throughput Optimize HDD:
      • This is a low-cost HDD designed for frequently accessed, throughput-intensive workloads
      • Volume Type: st1
      • Durability: 99.8%-99.9% (0.1 – 0.2% of annual failure rate)
      • Use cases:
        • Big Data
        • Data Warehouses
        • Log Processing
      • Volume Size: 125 GiB – 16 TiB
      • Max IOPS per volume: 500
      • Max Throughput per volume: 500 MiB/s
    • Cold HDD:
      • The lowest cost HDD designed for less frequently accessed workloads
      • Volume Type: sc1
      • Durability: 99.8%-99.9% (0.1 – 0.2% of annual failure rate)
      • Use cases:
        • Scenarios where lowest storage cost is important
        • infrequently accessed data
      • Volume Size: 125 GiB – 16 TiB
      • Max IOPS per volume: 250
      • Max Throughput per volume: 250 MiB/s
  • Previous generation:
    • Magnetic disk:
      • volume size: 1GiB – 1 TiB
      • Max IOPS => 40-200
      • Max Througput => 40-90 MiB/s
• To understand the EBS Volumes Better lets try to create a Price Estimate Refer Here.
• Lets try to estimate the cost for 200 GiB EBS Volume with different Volume Types.
