Object Storage versus Block Storage

Object Storage

Object Storage: Referred to as object-based storage. It is a general term that refers to the way in which we organize and work with units of storage, called objects. Every object consists of three things:

1. The Data itself.
2. Metadata.
3. A globally unique identifier.

Block Storage

Block Storage: Referred to as files getting split in to uniform pieces of chunks called as blocks. These blocks have their own independent address, but no metadata (additional information) to provide more context for what that block of data is.

You are likely to encounter block storage in majority of the enterprise workloads. It has wide variety of uses.
