Which storage type stores data as fixed-size blocks without metadata?
✗ Incorrect
Block storage divides data into fixed-size blocks and does not store metadata with each block.
Which storage type uses a hierarchy of files and folders?
✗ Incorrect
File storage organizes data in files and folders, similar to a traditional file system.
Which storage type is best suited for storing large amounts of unstructured data with metadata?
