Cloudflare R2 Storage allows developers to store large amounts of unstructured data without the costly egress bandwidth fees associated with typical cloud storage services.

​​ Object storage

Object storage is an architecture for storing and managing data in an unstructured format, and examples of unstructured data include photos, audio files, videos, and data lakes to name a few.

Object storage allows you to assign unique identifiers to each file, or object, which you can use to locate and access each object.

Object storage is best for data that needs to be read many times, such as audio or video files on your personal website.
