Amazon Elastic Block Store (Amazon EBS) provides persistent, block-level storage volumes for use with Amazon EC2 instances in the AWS SoftNAS®. Each Amazon EBS volume is automatically replicated within its Availability Zone to protect from component failure, offering high availability and durability. Amazon EBS and Buurst's SoftNAS® provide access to store and retrieve any amount of data, at any time, from anywhere on the web. It gives anyone access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to customers.
As an example: For 1 TB of usable storage with RAID Redundancy for increased performance and data redundancy, one potential configuration could be:
- Two 1 TB EBS volumes, configured as RAID 1 mirrors
- Five 250 GB EBS volumes, configured as RAID 5 (four data, single parity)
- Seven 250 GB EBS volumes, configured as RAID 6 with a spare (four data, dual parity, one spare)
