Object versus file versus block storage: What’s the difference?

This episode of Techsplainers explores the differences between object storage, file storage and block storage, helping listeners understand how each model organizes, stores and retrieves data. The episode explains how file storage uses familiar folders and files, why block storage is often chosen for databases and performance-sensitive workloads, and how object storage supports massive volumes of unstructured data with metadata-rich, API-based access. The discussion follows a clear comparison of how each storage model works, where it fits and what tradeoffs come with it. Listeners learn why file storage is intuitive for shared content and collaboration, why block storage gives applications more direct and efficient access to data, and why object storage is a strong fit for scale, archives, media libraries and cloud-native systems. The episode also highlights the benefits and limitations of each model around usability, latency, scalability and management. Rather than treating these as either-or technologies, the episode shows how many organizations use all three together to support a range of workloads across modern IT environments.
