storagetype

Storagetype is a broad label used in computing to distinguish categories of data storage according to how data is stored, accessed, and managed. It is used in IT architecture, cloud provisioning, and database design to differentiate assets by characteristics such as persistence, performance, interface, and cost.

Physical versus logical storage describes how data is stored and accessed. Physical storage refers to tangible media such as hard disk drives, solid-state drives, NVMe drives, and magnetic tape. Logical storage models describe how data is organized: block storage provides fixed-size blocks addressed by the system, file storage uses a hierarchical file system, and object storage stores data as discrete objects with metadata and a unique identifier. In terms of volatility, persistent storage retains data across power cycles, whereas volatile memory such as RAM loses data when power is lost.

Storage tiers and classes capture the idea of balancing performance and cost. Hot or active storage is used for frequently accessed data, while cold or archival storage is cheaper and intended for long-term retention. Cloud providers often offer distinct storage types with different durability and latency profiles, such as high-performance block storage, scalable object storage, and long-term archival storage.

Considerations when selecting a storagetype include durability, availability, scalability, throughput and latency requirements, access patterns, software compatibility, and total cost of ownership. The choice influences backup strategies, replication, disaster recovery, and compliance with data governance. Related concepts include block storage, file storage, object storage, and storage tiering across on-premises and cloud environments.
