  6. EBS - elastic block storage - can be mounted and file system created for use. can be attached to any single instance

EBS volumes are highly available and reliable storage volumes that can be attached to any running instance that is in the same Availability Zone.

For more information about Amazon EBS pricing, see the Projecting Costs section of the Amazon Elastic Block Store page.
