Block blobs

Block blobs are a type of data storage used in cloud services, like Azure Blob Storage, designed to handle large amounts of unstructured data such as videos, images, or documents. They are composed of multiple smaller units called blocks, each identifiable by a unique ID. This structure allows for efficient uploading, updating, and managing large files by uploading or modifying individual blocks rather than the entire file. Block blobs are flexible, enabling users to append new data and modify existing content without affecting the whole blob, making them ideal for scenarios requiring frequent updates or large-scale data storage.
