Abstract: Systems and methods for cache management of a storage device are disclosed. The storage device is configured to receive a first code provided by a computing device; execute the first code; perform a first update of the first storage medium based on the first code; receive a second code provided by the computing device; execute the second code; and perform a second update of the first storage medium based on the second code.

Abstract: Systems and methods for prefetching data are disclosed. A processor executes a first command for moving first data stored in a storage device. Based on the first command, the processor stores, into a first queue of the storage device, a first address associated with the first data. The storage device further retrieves the first address from the first queue, retrieves the first data from the first storage medium based on the first address, and stores the first data to the second storage medium. In some embodiments, a process for prefetch optimization is also disclosed. A processor identifies a value for prefetching data. The processor runs an application, measures performance of the application, modifies the value based on the performance, and determines that the performance satisfies a criterion.

Abstract: Systems and methods for prefetching data are disclosed. A processor in communication with a storage device identifies a first address. The processor identifies a first setting associated with the first address. The processor issues a first command to a first storage medium of the storage device based on the first setting. The first command is for performing a first type of memory read. The storage device is configured to retrieve first data associated with the first address in the first storage medium, to a second storage medium of the storage device, based on the first command.
