Elastic Block Store or EBS is the persistent store. It does behave and look identical to any disk, right, that you would typically mount and attach to your operating system. These disk drives can be allocated in sizes between 5 MB and 1 TB. You can mount multiple volumes of EBS storage and attach them to your machine. You can RAID these volumes just like you would normal hard disks. However, there is a charge for this storage. The charges are for reserved capacity. Based on the size of the drive that you've allocated, you'll be charged for whatever the size of the drive is on a monthly basis, and the prices are $0.10/GB/month.
