What type of storage is best suited for applications requiring high-speed access to data?

Hot storage is the best choice for applications that require high-speed access to data. This type of storage is designed for quick and immediate retrieval of data, making it ideal for applications that need rapid access, such as databases, online transaction processing (OLTP), and real-time analytics. Hot storage typically utilizes high-performance technologies, such as solid-state drives (SSDs) or high-speed disk arrays, which contribute to reduced latency and faster I/O operations.

In contrast, cold storage is typically used for data that is infrequently accessed, featuring slower access speeds and lower costs. Structured storage refers to the organization of data in a highly organized format but does not specifically imply speed. Backup storage is primarily focused on data redundancy and recovery rather than speed of access, making it less suitable for applications that require immediate data availability.
