Abstract
A storage device organizes data on different storage media based on access history and user behavior to accelerate data retrieval. The storage device includes a first storage media and a second storage media to store the data. The second storage media may be accessed faster than the first storage media. A controller on the storage device executes a first data retrieval to identify hot blocks in the first storage media based on the access history. The controller also executes a second data retrieval to identify the hot blocks in the first storage media based on a semantic search. The controller may prefetch the hot blocks from the first storage media, cache the prefetched hot blocks in the second storage media and/or move the hot blocks from a slower storage medium to a faster storage medium.
