Block Storage

---

:

Structure: Divides data into fixed-size blocks, each with a unique identifier.

Data Type: Typically used for **structured** data.

Use Case: Ideal for applications requiring frequent read/write operations, such as databases and virtual machines.

Performance: Fast access and retrieval times.

Scalability: Limited scalability; adding more storage requires additional blocks.

Example: SAN (Storage Area Network).

Object Storage

---

:

Structure: Stores data as objects, each with unique metadata and an identifier.

Data Type: Suitable for **unstructured** data.

Use Case: Suitable for storing large volumes of unstructured data, such as photos, videos, and backups.

Performance: Slower access times compared to block storage.

Scalability: Highly scalable; can store vast amounts of data easily.

Example: Amazon S3 (Simple Storage Service).
