A block device is a storage device that moves data in sequences of bytes or bits (blocks). These devices provide random access to fixes-size blocks of data 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.
