Object-based storage is indeed synonymous with file-based storage due to the way in which data is managed and accessed. In object storage, data is stored as discrete units called "objects," which provides a flexible structure that is beneficial for storing unstructured data such as images, videos, and backups.
Each object consists of the data itself, metadata, and a unique identifier, making it more versatile than traditional file systems that rely on a hierarchy to organize files. This architecture allows for easier scalability and management of large amounts of data, as the system can handle thousands or millions of objects without the complexities that come with a traditional file-based or block storage system.
Additionally, object storage systems can be accessed over HTTP and use RESTful APIs, which is characteristic of modern files systems aimed at cloud storage solutions. This makes object storage suitable for use cases like data archiving, big data analytics, and media content delivery, aligning closely with the principles of file-based storage systems, which also deal with individual files and their attributes.
In contrast, block storage is structured in fixed-size blocks and is typically used for databases and applications that require high performance, while database storage refers to structured data that is managed by a database management system. Raw storage is a more generalized term
