Suggested Answer: A 🗳️
A block device is a storage device that moves data in sequences of bytes or bits (blocks). These de-vices 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:
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)
The SSD, HDD and Magnetic choices are all options for the type of storage offered via EBS vol-umes. They are not types of block devices.
