About EBS Disks

Amazon Elastic Block Store (Amazon EBS) provides persistent block level storage volumes for use with Amazon EC2 (and SoftNAS) instances in the AWS Cloud. Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability. Amazon EBS volumes offer the consistent and low-latency performance needed to run your workloads.

AWS Access Key ID

The AWS Access Key is an authentication identifier which uniquely identifies an AWS(Amazon Web Services) account.

AWS Secret Key

The AWS Secret Key is the secret password component used to authenticate the AWS Access Key and provide access to Amazon EBS storage.

Maximum Disk Size

Enter a numeric value and choose the units (GB) representing the maximum size of the EBS disk. The EBS disk can provide up to 1024 GB of storage capacity.

Disk Encryption

EBS Disk contents can be encrypted and signed. When encryption is enabled, SHA1 HMAC authentication is also automatically enabled, and any blocks that are not properly encrypted and signed are rejected.

EBS Disk Type

Select the type of EBS Disk you would like to provision. Options include:

General Purpose:

General purpose SSD volume that balances price and performance for a wide variety of transactional workloads.

Provisioned IOPS:

Highest-performance SSD volume designed for mission-critical applications. Provisioned IOPS is configurable, allowing you to set an IOPS performance benchmark, allowing AWS to promise single-digit millisecond latencies and to deliver the provisioned performance 99.9% of the time. Configure the Provisioned IOPS threshold with the dropdown that appears below the option once selected.


Low Cost HDD volume can be used for workloads with smaller datasets where data is accessed infrequently or when performance consistency isn't of primary importance.

Throughput Optimized HDD:

Low cost HDD volume designed for frequently accessed, throughput-intensive workloads.

Cold HDD:

Lowest cost HDD volume designed for less frequently accessed workloads.

Delete Disk on Instance Termination

Determine whether the disk you are creating should be persistent, or whether it should be deleted upon termination of the host instance.


Enabling pre-warming avoids the initial performance penalty the first time each block is accessed.

However, the disk(s) will be inaccessible until the pre-warming is completed. This can take hours for large disks.

Number of EBS Disks

Select the number of EBS disks you wish to create with the defined settings.
