Data in block-level access is managed in discrete units referred to as "blocks." This method organizes data into fixed-size pieces, which allows for more efficient storage and retrieval. Block-level storage is commonly used in situations where high performance is necessary, such as in databases and applications requiring rapid access to individual pieces of data.

By managing data in blocks, systems can read or write different sections of the data independently, enabling faster access times and providing flexibility in how storage is utilized. This contrasts with other methods, such as file-level access, where entire files are treated as a single unit rather than being broken down into smaller, manageable components. Consequently, this approach offers benefits like improved performance for operations that modify or handle larger datasets and better utilization of storage space.
