Which type of Azure storage is best suited for large amounts of unstructured data?

Blob Storage is specifically designed for storing large amounts of unstructured data, such as text or binary data. This includes images, videos, audio files, and documents that do not have a specific data model or structure. The scalability and cost-effectiveness of Blob Storage make it ideal for applications that need to handle vast volumes of data. Additionally, it supports various access tiers (hot, cool, and archive), allowing for better management of storage costs based on data access patterns.

In contrast, File Storage is optimized for a file share that can be used by multiple virtual machines, while Queue Storage is intended for storing and retrieving messages between application components. Table Storage provides a NoSQL key-value store for structured data but is not suitable for unstructured data. These distinctions help illuminate why Blob Storage is the preferred choice for large quantities of unstructured data.
