    Abstract: In one embodiment, a processor comprises a processing core; and a cache controller to send a plurality of write requests to a cache storage device to store cache lines of a stream block, the plurality of write requests each including a stream identifier of the stream block, wherein a capacity of the stream block is equal to a capacity of an erase block of the cache storage device and wherein the erase block is dedicated to storing cache lines of the stream block; determine to evict the stream block from the cache storage device based upon a determination that space is not available in the cache storage device to cache data received from a first storage device; and send a deallocation request to the cache storage device to deallocate all cache lines of the stream block to enable the cache storage device to erase the erase block.

    Abstract: In one embodiment, a request to access a first storage location of a storage device may be received, wherein the storage device comprises a data storage and a cache. The cache may be accessed to obtain data for one or more second storage locations of the storage device, wherein the data for the one or more second storage locations has not been written to the data storage, and wherein the first storage location and the one or more second storage locations are located near each other on the data storage. The data storage may then be accessed in response to the request to access the first storage location of the storage device. The data storage may also be accessed to write the data for the one or more second storage locations obtained from the cache.
