Abstract
A system is provided. The system includes a storage controller configured to receive a prefetch command from a host interface. The storage controller includes a read cache memory that stores prefetch data in response to the prefetch command and a plurality of storage tiers coupled to the storage controller and providing the prefetch data. The plurality of storage tiers includes a fastest storage tier that stores the prefetch data if the read cache memory discards the prefetch data after storing the prefetch data.
