EBS Data Storage volumes are designed to be highly available and reliable. EBS volume data is replicated across multiple servers to prevent the loss of data from the failure of any single component.  As an example, volumes that operate with 20 GB or can expect an annual failure rate (AFR) of between 0.1% – 0.5%, where failure refers to a complete loss of the volume. This compares with commodity hard disks that will typically fail with an AFR of around 4%, making EBS volumes 10 times more re...
