Block Storage is a type of data storage that divides files into fixed-size blocks. Each block is stored separately and can be accessed independently, allowing for efficient data management. This method is commonly used in cloud computing and virtualization, where quick access to data is essential. Unlike file storage, which organizes data in a hierarchical structure, block storage treats each block as an individual unit. This makes it ideal for applications that require high performance, such as databases and enterprise applications. Additionally, block storage can be easily scaled, providing flexibility for growing data needs.
