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.

Also referred to as file storage.
Examples: Amazon Elastic File System (EFS).
Block Storage
Block storage is one of the infrastructure platform storage primitives exposed to the upper layer and usually dynamically managed through APIs. In an infrastructure platform, block storage is usually available in the form of virtual disk volumes. The block storage volume can be attached to a server or a container instance as if it was a local disk. Examples: Amazon Elastic Block Store (ESB) volumes, Azure Page Blobs, GCP Persistent Disk and OpenStack Cinder.
Block Device
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.
Object Storage
Object storage blobs: immutable, unstructured data such as images, videos and documents.
Examples: Amazon S3 service, Google Cloud Storage service, Azure Blob Storage.
