What is a typical use case for a block blob?

Block blobs are designed primarily for storing large amounts of unstructured data, such as text and binary data. They work best for scenarios in which data is not frequently modified after it is first uploaded. This makes them ideal for storing files such as images, videos, backups, and documents – content that is primarily appended or accessed rather than altered regularly.

In contrast to options like random read/write access or data that needs to be streamed continuously, block blobs are optimized for efficient upload and download operations, particularly for data that can be uploaded in blocks. This means that once data is stored in a block blob, it is typically kept in its original form without frequent changes, aligning perfectly with the described use case.

This understanding of block blobs highlights their strengths in handling large, immutable datasets, making them excellent for scenarios where once data is created, it will be accessed often but not modified, such as archiving purposes or cloud-based storage for static content.
