Question
Which storage class is for raw storage of data in fixed-sized chunks, each with a unique identifier?
A. File
B. Gateway
C. Object
D. Block
Answer
D. Block
Explanation
Block storage breaks up data into blocks and then stores those blocks as separate pieces, each with a unique identifier. They are stored wherever it is most effcient. Thus, this storage class can store those blocks across different systems, and each block can be configured to work with different operating systems.
Block storage is the storage class used for storing raw data in fixed-sized chunks, each with its own unique identifier. Some key characteristics of block storage:
- Data is stored in blocks or volumes of a predefined size, such as 512 bytes or 4KB
- Each block has a unique address or identifier that allows it to be stored and retrieved independently
- Provides low-level control over data storage and access
- Commonly used for structured data like databases or file systems where data needs to be accessed and modified at the block level
- Offers high performance and low latency
In contrast, other storage classes like file, object, and gateway storage have different data models and access patterns. File storage organizes data in a hierarchy of files and folders, object storage manages data as discrete units with metadata, and gateway storage provides protocol access to other storage systems.
So in summary, block storage is the storage class that deals with raw data in fixed-size, uniquely addressed blocks, making it ideal for high-performance, granular data storage and access.
