Block Storage

Noun · Development

Definitions

  1. A storage type that splits data into fixed-size blocks and stores them with unique addresses, mimicking a physical hard drive. Provides low-latency random access and is used for databases and OS volumes. AWS EBS, GCP Persistent Disks, and Azure Managed Disks are cloud examples.

    In plain English: Cloud storage that behaves like a hard drive attached to your server, with fast read/write access.

    Example: "Use block storage for the PostgreSQL data directory — object storage is too slow for random I/O database workloads."
