-Each instance has a root device volume.
-A block device is a storage device that moves data in sequences of bytes or bits (blocks). These devices support random access and generally use buffered I/O. Examples include hard disks, CD-ROM drives, and flash drives. A block device can be physically attached to a computer or accessed remotely as if it were physically attached to the computer.
-Amazon EC2 supports two types of block devices:
-* Instance store volumes  - virtual devices whose underlying hardware is physically attached to the host computer for the instance.
-* EBS volumes - remote storage devices.
