 EBS Volume Types

Amazon EBS provides the following volume types

Solid state drives (SSD) —

 Optimized for transactional workloads involving frequent read/write operations with small I/O size, where the dominant performance attribute is IOPS.

Solid state drives (SSD)

The SSD-backed volumes provided by Amazon EBS fall into these categories:

General Purpose SSD — Provides a balance of price and performance. We recommend these volumes for most workloads.

     gp3

       Durability:- 99.8% - 99.9% durability (0.1% - 0.2% annual failure rate)

     gp2

       Durability:- 99.8% - 99.9% durability (0.1% - 0.2% annual failure rate)

     Use Case

  •          Low-latency interactive apps
  •          Development and test environments

  1.   Volume Size   1 GiB - 16 TiB
  2.   Max IOPS per volume (16 KiB I/O) : 16000
  3.   Max throughput per volume : For gp3 1,000 MiB/s and for gp2 250 MiB/s* 
  4.   Amazon EBS Multi-attach : Not Supported
  5.   Boot volume: Supported

Provisioned IOPS SSD 

Provides high performance for mission-critical, low-latency, or high-throughput workloads. io2 Block Express ‡,io2,io1 are the types of Provisioned IOPS SSD.

     Durability:- 99.999% durability (0.001% annual failure rate), for io1 - 99.8% - 99.9% durability (0.1% - 0.2% annual failure rate)

     Use Case

         Workloads that require:

  •    Sub-millisecond latency
  •    Sustained IOPS performance
  •    More than 64,000 IOPS or 1,000 MiB/s of throughput

  1.     Volume Size :- 4 GiB - 64 TiB, for io1 - 4 GiB - 16 TiB
  2.      Max IOPS per volume (16 KiB I/O) :-  256,000 , for io1 64,000
  3.      Max throughput per volume 4000MiB/s, for io1 1000/MiB/s
  4.      Amazon EBS Multi-attach : Supported

Hard disk drives (HDD) — 

Optimized for large streaming workloads where the dominant performance attribute is throughput.

Volume: 125 GiB - 16 TiB

Use Cases

  • Big data
  • Data warehouses
  • Log processing


Previous generation — 

Hard disk drives that can be used for workloads with small datasets where data is accessed infrequently and performance is not of primary importance. We recommend that you consider a current generation volume type instead.

Use Case

Workloads where data is infrequently accessed

Volume size: 1GB to 1 TB
