Amazon Web Services is making solid state disks the standard storage for its Elastic Block Store service used with running instances, and is setting the price to compete with Google Compute Engine.
Solid state was available previously on Amazon’s EC2, but it tended to be associated with specialized server types designed to provide data management and high transaction throughput. The storage Amazon announced on Tuesday is general-purpose storage volumes based on SSDs, priced at $.10 per GB per month.
If general-purpose SSDs don’t provide a high enough input/output rate, customers can purchase additional capacity for $.125 per GB per month for each additional 1000 IOPS provisioned times. The cost is reduced by the share of the month in which they’re actually used — for example, if they are used for half the month, the bill would be 50% of what would otherwise be a month’s total.
