What is Data Storage

This episode of Techsplainers explores what data storage is and why it remains a foundational part of modern computing. It explains how storage differs from memory, how computers retain data over time, and why the growth of AI and IoT systems is increasing pressure on storage systems to scale efficiently. The episode walks through the main types of data storage: file, block and object storage, showing where each fits best in real-world environments. It also examines major storage architectures, including direct-attached storage, network-attached storage and storage area networks, highlighting the tradeoffs between simplicity, performance, cost and scalability. From SSDs and flash to cloud, hybrid cloud, AI and edge storage, the discussion follows how storage technologies are evolving to support new workloads. It also covers the growing role of storage in cybersecurity and compliance, including encryption, immutable snapshots, cyber resilience and recovery testing requirements in regulated industries. Finally, it introduces software-defined, virtualized and intelligent storage approaches that help organizations manage data more efficiently at scale.
