File System Tiered Storage Filter Driver SDK, is a data storage technique which automatically moves data between high-cost and low-cost storage media. Tiered Storage Filter systems exist because high-speed storage devices, such as hard disk drive arrays, are more expensive (per byte stored) than slower devices, such as network attached storage(NAS),optical discs and cloud storage.
Tiered storage can be widely used in telecommunications, government, oil, medical and other industries. .
