EBS Volume Types and Snapshots

EBS volume types

SSD, General Purpose – gp2

• Baseline of 3 IOPS per GiB with a minimum of 100 IOPS
• Burst up to 3000 IOPS (for volumes >= 334GB)
• Up to 16,000 IOPS per volume
• AWS designs gp2 volumes to deliver 90% of the provisioned performance 99% of the time. A gp2 volume can range in size from 1 GiB to 16 TiB.

SSD, Provisioned IOPS – i01

• More than 16,000 IOPS
• Up to 64,000 IOPS per volume
• Up to 50 IOPS per GiB
• Amazon EBS delivers the provisioned IOPS performance 99.9 percent of the time.

HDD, Throughput Optimized – st1

• Frequently accessed throughput intensive workloads with large datasets and large I/O sizes, such as MapReduce, Kafka, log processing, data warehouse, and ETL workloads
• Throughput measured in MB/s and includes the ability to burst up to 250 MB/s per TB, with a baseline throughput of 40 MB/s per TB and a maximum throughput of 500 MB/s per volume
• Cannot be a boot volume

HDD, Cold – sc1

• Lowest cost storage — cannot be a boot volume
• Less frequently accessed workloads with large, cold datasets
• These volumes can burst up to 80 MB/s per TB, with a baseline throughput of 12 MB/s per TB and a maximum throughput of 250 MB/s per volume.

Magnetic (Standard)

• Cheap, infrequently accessed storage that can be a boot volume
• Delivers around 100 IOPS on average

EBS optimized instances

• Dedicated capacity for Amazon EBS I/O
• EBS-optimized instances are designed for use with all EBS volume types.
• Max bandwidth: 400 Mbps – 12000 Mbps
• IOPS: 3000 – 65000
• GP-SSD within 10% of baseline and burst performance 99.9% of the time
• PIOPS within 10% of baseline and burst performance 99.9% of the time
• Additional hourly fee
• Available for select instance types
• Some instance types have EBS-optimized enabled by default.
