The correct answer is: D. all of the mentioned
A block storage device exposes its storage to clients as raw storage that can be partitioned to create volumes. A file storage device exposes its storage to clients as files. A disk storage device is a physical storage device that can be used to store data.
Block storage is a type of storage that provides raw, unformatted storage space to the operating system. This type of storage is often used for applications that require high performance, such as databases and file servers. Block storage is typically organized into logical units called blocks, which are typically 4KB in size.
File storage is a type of storage that stores data in files. Files are organized into directories, which are similar to folders on a computer. File storage is typically used for applications that do not require high performance, such as word processing and spreadsheets.
Disk storage is a type of storage that stores data on physical disks. Disks can be either magnetic disks or solid-state drives (SSDs). Magnetic disks are the traditional type of disk storage, while SSDs are a newer type of disk storage that is faster and more durable than magnetic disks.
In conclusion, all of the mentioned storage devices expose their storage to clients as raw storage that can be partitioned to create volumes.
