OSD (Object Storage Device)

An Object Storage Device (OSD) is a hardware component that stores data as discrete objects rather than traditional files or blocks. Each object includes the data itself, along with metadata and a unique identifier. This architecture allows for scalable, efficient storage of large amounts of unstructured data like photos, videos, or backups. OSDs are commonly used in data centers and cloud environments because they simplify data management, improve scalability, and enable quick access across distributed systems. Essentially, they serve as flexible, high-capacity storage units optimized for modern data needs.
